3 Description

The OPA2863-Q1 is a low-power, unity-gain stable, rail-to-rail input and output, voltage-feedback operational amplifier designed to operate over a power-supply range of 2.7 V to 12.6 V. Consuming only 700 µA per channel, the OPA2863-Q1 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 makes OPA2863-Q1 an excellent choice for general-purpose applications like current sensing and photodiode interface. 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 OPA2863-Q1 includes 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.
