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.

5k, 1% 6 LT1793 All of the examples shown use single-ended sensing
and an absolute minimum of external circuitry. Inputs
to the circuit shown range from high voltage DC to
ultraviolet light. Output data represents amplitude or
power levels for signals in all the AC inputs.

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 …
