Overview
z Signal Bandwidth: DC to 2 kHz z Selectable Gain: x1, x2, x4, x8, x16, x32, x64 z Differential Inputs, Differential Outputs Multiplexed inputs: INA, INB, 800Ω termination Rough / fine charge outputs for CS5371/72 Max signal amplitude: 5 Vpp differential Low input bias: 500 pA z Outstanding Noise Performance 0.20 µVp-p between 0.1 Hz and 10 Hz 8.5 nV/ Hz from 0.1 Hz to 2 kHz z Low Total Harmonic Distortion -118 dB THD typical (0.000126%) -112 dB THD maximum (0.000251%) z Low Power Consumption Normal/LPWR/PWDN: 5.5 mA, 3.5 mA, 10 µA z 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 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.
