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’s first true precision, dual high speed amplifier.
