... MUX1 INA- INB- http://www.cirrus.com Description The CS3301A is a low-noise differential input, dif- ferential output amplifier with programmable gain, optimized for amplifying signals from low-imped- ance sensors such as geophones. The gain settings are binary weighted (x1, x2, x4, x8, x16, x32, x64) and are selected using simple pin set- tings ...
