Description
The CS3301 is a low-noise differential input, differential
output amplifier with programmable gain, optimized for
amplifying signals from low-impedance sensors such as
geophones. 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 Ω termination can also be selected
for noise tests.
Amplifier noise performance is outstanding with a noise
density of 8.5
width. Distortion performance is also extremely good,
typically -118 dB THD. Flat noise down to 0.1 Hz and
low total harmonic distortion make this amplifier ideal for
low-frequency, low-amplitude, differential signals requir-
ing maximum dynamic range.
