The OPAx863A devices are low-power, unity-gain stable, rail-to-rail input and output, voltage-feedback operational amplifiers, trimmed in package to offer high precision performance with maximum input offset voltage of 95-µV and offset drift of 1.2-µV/℃ for high accuracy measurements over temperature.

Consuming only 800-µA per channel, the OPAx863A devices offer a gain-bandwidth product of 50-MHz, slew rate of 100-V/µs with a voltage noise density of 6.3-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 superior performance with wide-input dynamic range.

The OPAx863A devices include overload power limiting to limit the increase in IQ with saturated outputs, thereby preventing excessive power dissipation in power conscious battery-operated systems. The output stage is short-circuit protected, making it conducive to ruggedized environments.
