GENERAL DESCRIPTION
The OP249 is a high speed, precision dual JFET op amp, simi-
lar to the popular single op amp, the OP42. The OP249 outper-
forms available dual amplifiers by providing superior speed with
excellent dc performance. Ultrahigh open-loop gain (1 kV/mV
minimum), low offset voltage and superb gain linearity, makes
the OP249 the industry’s first true precision, dual high speed
amplifier.
With a slew rate of 22 V/µs typical, and a fast settling time of
less than 1.2 µs maximum to 0.01%, the OP249 is an ideal

choice for high speed bipolar D/A and A/D converter applica-
tions. The excellent dc performance of the OP249 allows the
full accuracy of high resolution CMOS D/As to be realized.
Symmetrical slew rate, even when driving large load, such as
600 or 200 pF of capacitance, and ultralow distortion, make
the OP249 ideal for professional audio applications, active fil-
ters, high speed integrators, servo systems and buffer amplifiers.
The OP249 provides significant performance upgrades to the
TL072, AD712, OP215, MC34082 and the LT1057.

1Absolute maximum ratings apply to both DICE and packaged parts, unless
otherwise noted.
2For supply voltages less than ± 18 V, the absolute maximum input voltage is equal
to the supply voltage.
3θJA is specified for worst case mounting conditions, i.e., θJA is specified for device
in socket for TO, cerdip, P-DIP, and LCC packages; θJA is specified for device
soldered to printed circuit board for SO package.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the OP249 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
