  Op Amp Selection Guide for Optimum Noise Performance
  Design Note 355
  Glen Brisebois
  Introduction
  Linear Technology continues to add to its portfolio of
  low noise op amps. This is not because the physics of
  noise has changed, but because low noise specifications are being combined with new features such as
  rail-to-rail operation, shutdown, low voltage and low
  power operation. Op amp noise is dependent on input
  stage operating current, device type (bipolar or FET)
  and input circuitry.This selection guide is intended to
  help you identify basic noise tradeoffs and select the
  best op amps, new or old, for your application.
  Quantifying Resistor Thermal
  Noise and Op Amp Noise
  The key to understanding noise tradeoffs is the fact that
  resistors have noise. At room temperature, a resistor
  R has an RMS voltage noise density (or “spot noise”)
  of VR = 0.13в€љR noise in nV/в€љHz. So a 10k resistor has
  13nV/в€љHz and a 1M resistor has 130nV/в€љHz. Rigorously
  speaking, the noise density is given by the equation
  VR = √4kTR, where k is Boltzman’s constant and T is
  the temperature in degrees Kelvin. This dependency ...

  Low-Distortion Sine Wave Oscillator with Precise RMS Amplitude Stability

  DESIGN IDEAS Low-Distortion Sine Wave Oscillator
  with Precise RMS Amplitude Stability
  by Cheng-Wei Pei
  Many applications require a frequency
  and/or amplitude-stable sine wave
  as a reference for calibration or measurement. Low harmonic distortion is
  also required for meaningful results
  in applications such as LVDT signal
  conditioning, ADC testing, and, of
  course, harmonic distortion testing.
  Many sine wave generation techniques simply cannot achieve the low
  harmonic distortion and amplitude
  stability required of a precision sine
  wave reference. The technique shown
  here generates a sine wave with less
  than 0.003% distortion and 0.1%
  amplitude stability.
  Figure 1 shows a simple oscillator
  circuit consisting of a Wien bridge
  oscillator core and an amplitude
  stabilization loop. The LT1632 highspeed low-distortion amplifier and its
  positive feedback RC network generate
  the oscillations. The amplitude, and ...

  Zero-Drift Op Amps Improve Performance and Save Power

  DESIGN FEATURES Zero-Drift Op Amps Improve
  Performance and Save Power
  by Brendan Whelan
  Introduction Performance and Features
  Lowest Power Across
  All Temperatures
  The LTC2054 and LTC2055 feature
  unprecedented low power dissipation,
  150ВµA max over temp per amplifier
  for the LTC2055 and 175ВµA max over
  temp for the LTC2054. This is five to
  seven times lower power than similar
  amplifiers, and makes these amplifiers ideally suited for battery-powered
  applications such as remote sensing.
  System design is simplified since the
  supply current is nearly constant
  over temperature (Figure 1), unlike
  with other amplifiers that specify low
  room temperature supply current
  but allow much higher consumption
  at temperature extremes. Start-up
  6 250 without adding significantly to input
  offset. When used in an integrator ...
