The FMC series contains a two-input, one output operational amplifier with a typical open loop gain of 80dB. The OPINP provides non-inverting amplifier input, while OPINN provides inverting amplifier input. The output is available at OPOUT. The key characteristics for the op-amp include: Frequency compensated for unity gain stability, Input common-mode range from GND to Vdd-.1V, Input offset voltage less than 15mV, Output voltage swing from GND+.1V to Vdd-.1V, and Input bias current less than 1nA.
