Description for the OPA863A
The OPA863A and OPA2863A devices (OPAx863A) are low-power, unity-gain stable, rail-to-rail input and output, voltage-feedback operational amplifiers. These devices are trimmed in package to offer high-precision performance with a maximum input offset voltage of 95µV and offset drift of 1.2µV/°C for high accuracy measurements over temperature.
Consuming only 800µA per channel, the OPAx863A offer a gain-bandwidth product of 50MHz, slew rate of 100V/µs, and a voltage noise density of 6.3nV/√Hz. The rail-to-rail input stage with 2.7V 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 OPAx863A 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 these devices conducive to ruggedized environments.
