The OPAx863 devices are low-power, unity-gain stable, rail-to-rail input and output, voltage-feedback operational amplifiers designed to operate over a power-supply range of 2.7 V to 12.6 V. Consuming only 700 µA per channel, the OPAx863 offers a gain-bandwidth product of 50 MHz, slew rate of 105 V/µs with a voltage noise density of 5.9 nV/√Hz.

The rail-to-rail input stage with 2.7-V supply operation is useful in portable, battery-powered applications. The rail-to-rail input stage is well-matched for gain-bandwidth product and noise across the full input common‑mode voltage range, enabling excellent performance with wide-input dynamic range. The OPAx863 feature a power-down (PD) mode with a PD quiescent current (I Q) of 1.5-µA (maximum) and a turn-on or turn-off time within 6.5-µs using a 3-V supply.

The OPAx863 includes overload power limiting to limit the increase in I Q with saturated outputs, thereby preventing excessive power dissipation in power-conscious, battery-operated systems. The output stage is short-circuit protected, making these devices conducive to ruggedized environments.
