LT1792/LT1464 Low Noise Hydrophone Amplifier with DC Servo

Nov 26th 1996
These op amps are best used with very high impedance transducers. The low noise hydrophone amplifier in this figure is an application where the LT1792 excels. The AC current output of the hydrophone is converted to a voltage output by the 100M input resistor (R8). This signal is amplified by the R3/R2 ratio. DC leakage currents ...

LT1169 Low Noise Hydrophone Amplifier with DC Servo

May 2nd 1994
The LT1169 achieves a new standard of excellence in noise performance for a dual JFET op amp. For the first time low voltage noise (6nV/rtHz) is simultaneously offered with extremely low current noise (1fA/rtHz), providing the lowest total noise for high impedance transducer applications. Unlike most JFET op amps, the very low ...
