ADI AD745JN

J-FET20 МГц

Overview

The AD745JN is an ultralow noise, high speed, FET input operational amplifier. It offers both the ultralow voltage noise and high speed generally associated with bipolar input op amps and the very low input currents of FET input devices. Its 20 MHz bandwidth and 12.5 V/µs slew rate makes the AD745JN an ideal amplifier for high speed applications demanding low noise and high dc precision. Furthermore, the AD745JN does not exhibit an output phase reversal.The AD745's guaranteed, tested maximum input voltage noise of 4 nV/(root)Hz at 10 kHz is unsurpassed for a FET-input monolithic op amp, as is its maximum 1.0 µV p-p noise in a 0.1 Hz to 10 Hz bandwidth. The AD745JN also has excellent dc performance with 250 pA maximum input bias current and 0.5 mV maximum offset voltage.

The AD745JN is available in 8-pin plastic mini-DIP, 8-pin cerdip, 16-pin SOIC, or in chip form.
