资 源 简 介
The AD743 is an ultralow noise, precision, FET input, monolithicoperaTIonal amplifier. It offers a combinaTIon of the ultralow voltagenoise generally associated with bipolar input op amps andthe very low input current of a FET input device. Furthermore,the AD743 does not exhibit an output phase reversal when thenegaTIve common-mode voltage limit is exceeded.The AD743’s guaranteed, maximum input voltage noise of4.0 nV/√Hz at 10 kHz is unsurpassed for a FET input monolithicop amp, as is the maximum 1.0 μV p-p, 0.1 Hz to 10 Hznoise. The AD743 also has excellent dc performance with 250 pAmaximum input bias current and 0.5 mV maximum offset voltage.The AD743 is specifically designed for use as a preamp in capaciTIvesensors, such as ceramic hydrophones. The AD743J is ratedover the commercial temperature range of 0°C to 70°C.The AD743 is available in a 16-lead SOIC and 8-lead PDIP.
