Cirrus Logic CS3302
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.| Part No. | CS3302 |

FEATURES
DESCRIPTION
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 Two sets of external inputs, INA and INB, simplify system design as inputs from a sensor and test DAC. An internal 800Ω termination can also be selected for noise tests. Amplifier input impedance is very high, requiring less than 1 pA of input current. Noise performance is very good at 1 µVp-p between 0.1 Hz and 10 Hz, and a noise density of 8.5 nV/ √Hz over the 200 Hz to 2 kHz bandwidth.
