Features Typical Values, TA = 25°C Gain error (over temperature range) LMP8100A 0.03% LMP8100 0.075% Gain range 1 to 16 V/V in 1 V/V steps Programmable frequency compensation Input zero calibration switch Input offset voltage (max, LMP8100A) 250 μV Input bias current 0.1 pA Input noise voltage 12 nV/ √Hz Unity gain bandwidth 33 MHz Slew rate 12 V/μs Output current 20 mA Supply voltage range 2.7V to 5.5V Supply current 5.3 mA Rail-to-Rail output swing V + −50 mV to V − +50 mV Description 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-to-rail 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. The amplifier features several programmable controls including: gain; a power-conserving shutdown mode which can reduce current consumption to only 20 μA; an input zeroing switch which allows the output offset voltage to be measured to facilitate system calibration; and four levels of internal frequency compensation which can be set to maximize bandwidth at the different gain settings. The LMP8100 comes in a 14-Pin SOIC package. Applications • Industrial instrumentation • Data acquisition systems • Test equipment • Scaling amplifier • Gain control • Sensor interface

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
