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.
