GENERAL DESCRIPTION
The OP249 is a high speed, precision dual JFET op amp, similar to
the popular single op amp, the OP42. The OP249 outperforms
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鈥檚 first true precision, dual high speed
amplifier.
With a slew rate of 22 V/渭s typical and a fast settling time of less
than 1.2 渭s maximum to 0.01%, the OP249 is an ideal choice for
high speed bipolar DAC and ADC applications. The excellent
dc performance of the OP249 allows the full accuracy of high
resolution CMOS DACs to be realized.
0.01
Symmetrical slew rate, even when driving large load, such as,
600 惟 or 200 pF of capacitance and ultralow distortion, make
the OP249 ideal for professional audio applications, active filters,
high speed integrators, servo systems, and buffer amplifiers.
The OP249 provides significant performance upgrades to the
TL072, AD712, OP215, MC34082, and LT1057.
