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 singleor 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).

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
THERMAL RESISTANCE
θJA is specified for the worst-case conditions, that is, a device
soldered in the circuit board for the surface-mount packages.
