24-Bit ADC Measures from DC to Daylight вЂ“ Design Note 219
Derek Redmayne
The need to measure a wide variety of physical phenomena is increasingly important in intelligent sensors. The
following circuit gives eight examples of the п¬‚exibility of
the LTC В®2408 for sensing real world phenomena. The
eight inputs of the LTC2408 are used here in a variety
of ways that would not be practical without the dynamic
range of the LTC2408.

LT1806: 325MHz Low Noise Rail-to-Rail SOT-23 Op Amp Saves Board Space &mdash DN254

325MHz Low Noise Rail-to-Rail SOT-23 Op Amp
Saves Board Space вЂ“ Design Note 254
Glen Brisebois
The new tiny LTВ®1806 combines 325MHz gain bandwidth, 3.5nV/в€љHz voltage noise, 100ОјV input offset
voltage and rail-to-rail inputs and outputs in a SOT-23
package. The device is fully speciп¬Ѓed on 3V, 5V and
В±5V supplies with a guaranteed maximum input offset
voltage of 850ОјV at either rail over temperature. It is
available in commercial and industrial temperature
grades.
1MО© Transimpedance Ampliп¬Ѓer Achieves Near
Theoretical Noise Performance with Large-Area
Photodiodes
The circuit of Figure 1 shows the LT1806 in an ultralow
noise transimpedance ampliп¬Ѓer applied to a large-area
high capacitance photodiode. The LT1806 is used for its
high gain bandwidth and low noise. The IFN147 ultralow
noise JFET1 operates at its IDSS (VGS = 0V) with a typical
transconductance of 40mS. With its source grounded,
the JFET and its drain resistor, R52, set a voltage gain
of about 8. The combination of the ultralow noise JFET
gain stage and the LT1806 low noise ampliп¬Ѓer achieves
the ultralow input noise performance. The circuitвЂ™s input …

1MW Transimpedance Amplifier Achieves Near-Theoretical Noise Performance, 2.4GHz Gain Bandwidth, with Large-Area Photodiodes &mdash LT Journal

DESIGN IDEAS 1Mв„¦ Transimpedance Amplifier
Achieves Near-Theoretical Noise
Performance, 2.4GHz Gain Bandwidth,
with Large-Area Photodiodes by Glen Brisebois
transimpedance circuitвЂ™s noise gain,
which applies to voltage noise but not
to current noise or resistor noise,
rises drastically with frequency (noise
gain = 1+ ZF/XC). As a sample calculation, a 500pF photodiode has an
impedance of 3.2k at 100kHz, giving
a 1Mв„¦ transimpedance circuit a noise
gain of 314 at that frequency. The
theoretical noise floor of the 1M
resistor is 130nV/в€љHz (at room temperature), so any input voltage noise
above 0.41nV/в€љHz (130nV/в€љHz/314)
will overtake the resistor noise at
100kHz. Discrete JFETs are available
with ultralow voltage noise but they
have high input capacitance (75pF
max for the IFN147). Serendipitously,
the input capacitance of the JFET is
relatively insignificant compared to
the 500pF of the example large-area …

DESIGN FEATURES JFET Op Amps Equal Low Noise
Bipolars and Have Picoamp
by Alexander Strong
Current Noise
The LT1792 and LT1793 are single
JFET op amps that offer both very low
voltage noise (4nV/в€љHz for the LT1792
and 6nV/в€љHz for the LT1793) and low
current noise (10fA/в€љHz for the
LT1792 and 0.8fA/в€љHz for the
LT1793), providing the lowest total
noise over a wide range of transducer
impedance. Traditionally, op amp
users have been faced with a choice:
which op amp will have the lowest
noise for the transducer at hand. For
high transducer impedance, the
LT1792/LT1793 JFET op amps will
win over the lowest voltage noise
bipolar op amps due to lower current
noise. The current noise (2qIB) of an
amplifier is a function of the input
bias current (IB). For lower transducer impedance, bipolar op amps …
