Overview
Signal bandwidth: DC to 2 kHz Selectable gain: x1, x2, x4, x8, x16, x32, x64 Differential inputs, differential outputs Multiplexed inputs: INA, INB, 800Ω termination Rough / fine charge outputs for CS5371/72 Max signal amplitude: 5 Vp-p differential Ultra-low input bias: < 1 pA Excellent noise performance 1 µVp-p between 0.1 Hz and 10 Hz 8.5 nV/ √Hz from 200 Hz to 2 kHz Low total harmonic distortion -118 dB THD typical (0.000126%) -112 dB THD maximum (0.000251%) Low power consumption Normal / LPWR / PWDN: 5 mA, 3.3 mA, 10 µA Single or dual power supply configurations VA+ = +5 V; VA- = 0 V; VD = +3.3 V to +5 V VA+ = +2.5 V;VA- = -2.5 V;VD = +3.3 V The CS3302 is a high input impedance differential in, differential 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.
