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 devices offer 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 superior performance with wide-input dynamic range. The OPA863 features a power-down (PD) mode with a PD quiescent current (IQ) of 1.5-µA (maximum) with turn-on or turn-off within 6.5-µs with a 3-V supply.
The OPAx863 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.
