OP249AZ

The OP249AZ is a precision high speed dual JFET Operational Amplifier for use with active filters. The OP249 outperforms available dual amplifiers by providing superior speed with excellent DC performance. Ultrahigh open-loop gain (1kV/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 22V/µs typical and a fast settling time of less than 1.2µs 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, 600R or 200pF of capacitance and ultralow distortion, make the OP249 ideal for active filters, high speed integrators, servo systems and buffer amplifiers.
