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.
