... MUX1 INA- INB- http://www.cirrus.com Description The CS3302 is a high-input-impedance, differential in- put, differential output amplifier with programmable gain, optimized for amplifying signals from high-impedance sensors such as hydrophones. The gain settings are bi- nary weighted (x1, x2, x4, x8, x16, x32, x64) and are selected using simple pin settings. Two sets of external ...
