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/
μ
s typical, and a fast settling time of
less than 1.2
μ
s 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.
