OP249GPZ

OP249 is a high speed, precision dual JFET op-amp, similar to the popular single op-amp. It out performs available dual amplifiers by providing superior speed with excellent dc performance. Ultra high open-loop gain (1KV/mV minimum), low offset voltage, and superb gain linearity makes the device 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%, It is an ideal choice for high speed bipolar DAC and ADC applications. The excellent dc performance of the device allows the full accuracy of high resolution CMOS DACs to be realized. It is used in applications such as output amplifier for fast DACs, signal processing, instrumentation amplifiers, fast sample-and-holds, active filters, low distortion audio amplifiers, input buffer for ADCs, servo controllers.
