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 V systems.

Fabricated on Analog Devices, Inc., 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 a high

slew rate, high bandwidth, with open-loop gain exceeding

40,000 and offset voltage under 800 Ω (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

temperature range (−40°C to +125°C).
