APPLICATIONS  
P RO D UCT H IGH LIGH TS  
Sonar Pream plifiers  
1. T he low offset voltage and low input offset voltage drift of  
the AD743 coupled with its ultralow noise performance  
mean that the AD743 can be used for upgrading many  
applications now using bipolar amplifiers.  
High Dynam ic Range Filters (>140 dB)  
Photodiode and IR Detector Am plifiers  
Accelerom eters  
2. T he combination of low voltage and low current noise make  
the AD743 ideal for charge sensitive applications such as  
accelerometers and hydrophones.  
P RO D UCT D ESCRIP TIO N  
T he 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.  
3. T he low input offset voltage and low noise level of the  
AD743 provide >140 dB dynamic range.  
4. T he typical 10 kHz noise level of 2.9 nV/√Hz permits a three  
op amp instrumentation amplifier, using three AD743s, to be  
built which exhibits less than 4.2 nV/√Hz noise at 10 kHz  
and which has low input bias currents.  
T he 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. T he AD743 also has excellent dc performance with  
250 pA maximum input bias current and 0.5 mV maximum  
offset voltage.

T he AD743 is specifically designed for use as a preamp in  
capacitive sensors, such as ceramic hydrophones. It is available  
in five performance grades. T he AD743J and AD743K are rated  
over the commercial temperature range of 0°C to +70°C. T he  
AD743A and AD743B are rated over the industrial temperature  
range of –40°C to +85°C. T he AD743S is rated over the  
military temperature range of –55°C to +125°C and is available  
processed to MIL-ST D-883B, Rev. C.
