Description

The CS3302 is a high-input-impedance, differential input, differential output 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. Two sets of external inputs, INA and INB, simplify system design as inputs from a sensor and test DAC. An internal 800? termination can also be selected for noise tests.
