GENERAL DESCRIPTION

The OP292/OP492 are low cost, general purpose dual and quad

operational amplifiers designed for single-supply applications

and are ideal for 5 olt systems.

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.
