Fabricated on Analog Devices’ CBCMOS process, the OP292/
OP492 series has a PNP input stage that allows the input voltage
range to include ground. A BiCMOS output stage enables the
output to swing to ground while sinking current.
The OP292/OP492 series is unity-gain stable and features an
outstanding combination of speed and performance for single-
or dual-supply operation. The OP292/OP492 provide high slew
rate, high bandwidth, with open-loop gain exceeding 40,000
and offset voltage under 800 ꢀ (OP292) and 1 mV (OP492).
With these combinations of features and low supply current, the
OP292/OP492 series is an excellent choice for battery-operated
applications.
The OP292/OP492 series performance is specified for single- or
dual-supply voltage operation over the extended industrial tem-
perature range (–40∞C to +125∞C).
Package options for the OP292 and OP492 include plastic DIP,
SO-8 (OP292) and SO-14.
