3 Instructions

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

Rail-to-rail input stages with 2.7-volt supply operation are useful in portable battery-powered applications. The differential input stage is well matched to gain-bandwidth product and noise over the entire input common-mode voltage range, enabling excellent performance over a wide input dynamic range. The OPA863 employs a power-down (PD) mode with a PD quiescent current of 1.4-µa (max), which turns on or off in 6.5-µs (typ).

The OPAx863 device includes an overload power limit to limit the increase in saturated output quiescent current to prevent excessive losses in battery powered systems. The output stage is short circuit protected, making it a rugged amplifier for general purpose use.
