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-torail

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 powerconscious,

battery-operated systems. The output

stage is short-circuit protected, making these devices

conducive to ruggedized environments.
