3 Description

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 highprecision

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 gainbandwidth

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 powerconscious,

battery-operated systems. The output

stage is short-circuit protected, making these devices

conducive to ruggedized environments.
