GENERAL DESCRIPTION
The OP249 is a high speed, precision dual JFET op amp, similar
to the popular single op amp. 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’s first true precision, dual high speed amplifier.
With a slew rate of 22 V/s typical and a fast settling time of less
than 1.2 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.
Symmetrical slew rate, even when driving large load, such as,
600 Ω 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.
