The LMP8100 programmable gain amplifier features an adjustable gain from 1 to 16 V/V in 1 V/V increments. At the core of the LMP8100 is a precision, 33 MHz, CMOS input, rail-torail input/output operational amplifier with a typical open-loop gain of 110 dB. Amplifier closed-loop gain is set by an array of precision thin-film resistors. Amplifier control modes are programmed via a serial port that allows devices to be cascaded so that an array of LMP8100 amplifiers can be programmed by a single serial data stream. The control mode registers are double buffered to insure glitch-free transitions between programmed settings. The LMP8100 is part of the LMP precision amplifier family and is ideal for a variety of applications.
