AD745 Datasheet PDF

●PRODUCT DESCRIPTION

●The AD745 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 AD745 an ideal amplifier for high-speed applications demanding low noise and high dc precision. Furthermore, the AD745 does not exhibit an output phase reversal.
