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