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 offers a gainbandwidth
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 gainbandwidth
product and noise across the full input
common‑mode voltage range, enabling excellent
performance with wide-input dynamic range. The
OPAx863 feature a power-down (PD) mode with a
PD quiescent current (IQ) of 1.5-μA (maximum) and
a turn-on or turn-off time within 6.5-μs using a 3-V
supply.
The OPAx863 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.
