AD8542ARZ-REEL, Op Amp Dual GP R-R I/O 5.5V Medical 8-Pin SOIC N T/R

AD8542 is a dual channel, rail-to-rail input and output, single-supply amplifier. Very low input bias currents enable this amplifier to be used for integrators, photodiode amplifiers, piezoelectric sensors, and other applications with high source impedance. Rail-to-rail inputs and outputs are useful to designers buffering ASICs in single-supply systems. This amplifier is optimized to maintain high gains at lower supply voltages, making them useful for active filters and gain stages.
