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 industrys first true precision, dual high speed  
amplifier.  
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.  
The OP249 provides significant performance upgrades to the  
TL072, AD712, OP215, MC34082, and LT1057.  
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 DAC and ADC applications. The excellent  
dc performance of the OP249 allows the full accuracy of high  
resolution CMOS DACs to be realized.
