3 Description
The OPAx863 devices are low-power, unity-gain
stable, rail-to-rail input and output, voltage-feedback
operational amplifiers designed to operate over a
power supply range of 2.7-V to 12.6-V. Consuming
only 700-μA per channel, the OPAx863 devices offer
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 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
OPA863 features a power-down (PD) mode with a
PD quiescent current (IQ) of 1.5-μA (maximum) with
turn-on or turn-off within 6.5-μs with a 3-V supply.
The OPAx863 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.
