Description
The CS3302 is a high input impedance differential in, dif-
ferential out amplifier with programmable gain, optimized
for amplifying signals from high impedance sensors such
as hydrophones. The gain settings are binary weighted
(x1, x2, x4, x8, x16, x32, x64) and are selected using
simple pin settings. Two sets of external inputs, INA and
INB, simplify system design as inputs from a sensor and
test DAC. An internal 800
termination can also be se-
lected for noise tests.
Amplifier input impedance is very high, requiring less
than 1 pA of input current. Noise performance is very
good at 1

p-p
between 0.1 Hz and 10 Hz, and a noise
density of 8.5 nV/

Hz over the 200 Hz to 2 kHz band-
width. Distortion performance is also extremely good,
typically -118 dB THD. Low input current, low noise, and
low total harmonic distortion make this amplifier ideal for
high impedance differential sensors requiring maximum
dynamic range.
