AD743 - Ultralow Noise BiFET Op Amp

Description

The AD743 is an ultralow noise, precision, FET input, monolithic operational amplifier.

It offers a combination of the ultralow voltage noise generally associated with bipolar input op amps and the very low input current of a FET input device.

Features

  • Ultralow Noise Performance 2.9 nV/√Hz at 10 kHz 0.38 ␮V p-p, 0.1 Hz to 10 Hz 6.9 fA/√Hz Current Noise at 1 kHz Excellent DC Performance 0.5 mV Max Offset Voltage 250 pA Max Input Bias Current 1000 V/mV Min Open-Loop Gain AC Performance 2.8 V/␮s Slew Rate 4.5 MHz Unity-Gain Bandwidth THD = 0.0003% @ 1 kHz Available in Tape and Reel in Accordance with EIA-481A Standard.
