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.
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 0.8 mV (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.
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 performance is specified for single- or
dual-supply voltage operation over the extended industrial
temperature range (−40°C to +125°C).
