Description:

The CS3302-IS is a high input impedance differential in, differential out amplifier with programmable gain. It is 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 can be easily selected using pin settings. The CS3302-IS features two sets of external inputs, INA and INB, which simplify system design by allowing inputs from a sensor and test DAC. Additionally, it has an internal 800Ω termination that can be selected for noise tests.
