  High Speed Amplifier Techniques
  A Designer’s Companion for Wideband Circuitry
  Jim Williams PREFACE
  This publication represents the largest LTC commitment
  to an application note to date. No other application note
  absorbed as much effort, took so long or cost so much.
  This level of activity is justified by our belief that high speed
  monolithic amplifiers greatly interest users.
  Historically, monolithic amplifiers have represented packets of inexpensive, precise and controllable gain. They
  have partially freed engineers from the constraints and
  frustrations of device level design. Monolithic operational
  amplifiers have been the key to practical implementation
  of high level analog functions. As good as they are, one
  missing element in these devices has been speed.
  Devices presently coming to market are addressing monolithic amplifiers’ lack of speed. They bring with them the
  ease of use and inherent flexibility of op amps. When Philbrick Researches introduced the first mass produced
  op amp in the 1950’s (K2-W) they knew it would be used.
  What they couldn’t possibly know was just how widely,
  and how many different types of applications there were.
  As good a deal as the K2-W was (I paid $24.00 for mine or rather, my father did), monolithic devices are far better.
  The combination of ease of use, economy, precision and …

  Application Note 57

  Video Circuit Collection
  Jon Munson and Frank Cox
  INTRODUCTION
  Even in a time of rapidly advancing digital image processing, analog video signal processing still remains eminently
  viable. The video A/D converters need a supply of properly
  amplified, limited, DC restored, clamped, clipped, contoured, multiplexed, faded and filtered analog video before
  they can accomplish anything. After the digital magic is
  performed, there is usually more amplifying and п¬Ѓltering
  to do as an adjunct to the D/A conversion process, not to mention all those pesky cables to drive. The analog way
  is often the most expedient and efficient, and you don’t
  have to write all that code.
  The foregoing is only partly in jest. The experienced engineer
  will use whatever method will properly get the job done;
  analog, digital or magic (more realistically, a combination
  of all three). Presented here is a collection of analog video
  circuits that have proven themselves useful. CIRCUIT INDEX

  High Frequency Amplifier Evaluation Board – Design Note 50
  Mitchell Lee
  Introduction
  Demo board DC009 is designed to simplify the evaluation
  of high speed operational amplifiers. It includes both an
  inverting and non-inverting circuit, and pads are provided
  to allow the use of board-mounted BNC or SMA connectors.
  The two circuits are independent, with the exception of
  shared power supply and ground connections. High Speed Layout Techniques grounds are still separated. For example, the termination
  resistors (R3 and R7) and the gain-setting resistor (R1)
  are grounded in the vicinity of the input connector. Supply
  bypass capacitors (C1, C2, C4, C5, C7, C8, C9, and C10)
  are returned to ground in the vicinity of the output
  connectors. Optional Components Layout is a primary contributor to the performance of any
  high speed amplifier. Poor layout techniques adversely
  affect the behavior of a finished circuit. Several important
  layout techniques, all used in demo board DC009, are
  described below: The circuit board is designed to accommodate standard 8pin miniDIP, single operational amplifiers, such as the
  LT1190 and LT1220 families. Both voltage and current
  feedback types can be used. Pins 1, 5, and 8 are outfitted
  with pads for use in adjusting DC offsets, compensation
  or, in the case of the LT1223 and LT1190/1/2, for shutting
  down the amplifier. Top Side Ground Plane: The primary task of a ground …

  New Low Cost Differential Input Video Amplifiers Simplify
  Designs and Improve Performance – Design Note 55
  John Wright
  The LT®1190 is a family of high speed amplifiers optimized for video performance on ±5V or single +5V
  supplies. The family includes three voltage feedback op
  amps and two video difference amplifiers. All amplifiers
  slew at 450V/Ојs, and deliver В±50mA output current for
  driving cables. The LT1193 video difference amplifier
  features uncommitted high input impedance (+) and
  (–) inputs, and can be used in differential or single-ended
  configurations. In addition, the LT1193 has an adjustable
  gain of two or greater, with a –3dB bandwidth of 80MHz.
  Wideband Voltage Controlled Amplifier
  The LT1193 video difference amplifier combined with an
  MC1496 balanced modulator make a low cost 50MHz
  Voltage Controlled Amplifier (VCA), shown in Figure 1.
  The input signal of the MC1496 at pin 1 is multiplied
  by the Control Voltage on Pin 10, and appears as a
  differential output current at Pins 6 and 12. The LT1193
  acts to level shift the differential signal and convert it
  to a single-ended output. Resistor RB is used to set the
  bias current in the MC1496 to 1mA in each 200О© RL,
  while RCM is used to shift the differential output into …

  Video Circuits Collection – Design Note 57
  William H. Gross
  Introduction
  This note shows how to make several different video
  circuits using high speed op amps. All of these circuits
  work with composite, RGB and monochrome video.
  For best results, bypass the power supply pins of
  these amplifiers with 1μF to 10μF tantalum capacitors
  in parallel with 0.01ОјF disc capacitors. It is important
  to terminate both ends of video cables to preserve
  frequency response. When properly terminated, the
  cable looks like a resistive load of 150О©.
  Lots of Inputs Video MUX Cable Driver (LT1227) Multiplex Amplifiers
  Often it is desirable to select one of several signals to
  send down a cable. Connecting the outputs of several
  amplifiers together and using the amplifier’s shutdown
  pin to disable all but one accomplishes this goal. The
  LTВ®1190, LT1191, LT1192, and LT1193 are shutdown by
  pulling pin 5 to the negative supply.
  The LT1223 and LT1227 current feedback amplifiers are
  shutdown by pulling Pin 8 to ground. During normal
  operation Pin 8 is open and at the positive supply potential. An easy way to interface Pin 8 to logic is with
  a logic level N-channel FET or a 74C906 (open-drain …

  Peak Detectors Gain in Speed and Performance &mdash DN61

  Peak Detectors Gain in Speed and Performance – Design Note 61
  John Wright
  Introduction
  Fast peak detectors place unusual demands on amplifiers. High slew rate is needed to keep the amplifier
  internal nodes from overracing the output stage. This
  condition causes either a long overload, or DC accuracy
  errors. To support the high slew rate at the output, the
  amplifier must deliver large currents into the capacitive
  load of the detector. Compounding these problems are
  issues of amplifier instability with a large capacitive
  load, as well as the accuracy of the output voltage.
  Detecting Sinewaves
  The LTВ®1190 is the ideal candidate for this application,
  with a high 400V/Ојs slew rate, large 50mA output
  current, and a wide 70 degree phase margin. The
  closed-loop peak detector circuit of Figure 1 uses a
  Schottky diode inside the feedback loop to obtain good
  accuracy. The 20О© resistor RO isolates the 0.01ОјF load
  and prevents oscillation. The DC error with a sine wave
  input is plotted in Figure 2 for various input amplitudes.
  The DC value is read with a DVM. At low frequency, the
  error is small and dominated by decay of the detector
  capacitor between cycles. As frequency rises the error …

  Send Color Video 1000 Feet Over Low Cost Twisted-Pair &mdash DN65

  Send Color Video 1000 Feet Over Low Cost Twisted-Pair
  Design Note 65
  John Wright
  It is now possible to send and receive color composite video signals appreciable distances on a low cost
  twisted-pair. This technique is similar to the push toward
  twisted-pair cables in EtherNet systems to replace
  costly coaxial cable connections. The cost advantage of
  these techniques is significant. Standard 75Ω RG-59/U
  coaxial cable costs between 25Вў and 50Вў per foot, but
  a PVC twisted-pair is only pennies per foot. This means
  hundreds of dollars are saved in installations as short
  as 1000 feet, easily paying for additional electronics.
  The system also provides for “drops” or receiver taps
  along the twisted-pair. This bidirectional “video bus” consists of the low cost
  LT®1190 op amp and the LT1193 video difference amplifier shown in Figure 1. A pair of LT1190s at TRANSMIT 1,
  is used to generate differential signals to drive the line
  which is back-terminated in its characteristic impedance.
  These amplifiers have high 50mA load driving ability,
  while maintaining a very high 450V/Ојs slew rate and
  50MHz gain-bandwidth. The twisted-pair receiver is an
  LT1193 video difference amplifier at RECEIVE 1, and it
  converts signals from differential to single-ended. The
  LT1193 offers features unavailable with other op amp …
