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. Furthermore,
the AD743 does not exhibit an output phase reversal when the
negative common-mode voltage limit is exceeded.
The AD743’s guaranteed, maximum input voltage noise of
4.0 nV/√Hz at 10 kHz is unsurpassed for a FET input monolithic
op amp, as is the maximum 1.0 μV p-p, 0.1 Hz to 10 Hz
noise. The AD743 also has excellent dc performance with 250 pA
maximum input bias current and 0.5 mV maximum offset voltage.
The AD743 is specifically designed for use as a preamp in capacitive
sensors, such as ceramic hydrophones. The AD743J is rated
over the commercial temperature range of 0°C to 70°C.
The AD743 is available in a 16-lead SOIC and 8-lead PDIP.
