CS3301A
Overview
The CS3301A is a low-noise differential input, differential output amplifier with programmable gain, optimized for amplifying signals from low-impedance sensors such as geophones. The gain settings are binary weighted (x1, x2, x4, x8, x16, x32, x64) and are selected using simple pin settings.
