Hydrophone Preamplifier based on Op-Amp OPA37

Published:2013/3/13 1:08:00 Author:Ecco | Keyword: Hydrophone Preamplifier | From:SeekIC

This is Hydrophone preamplifier circuit diagram, designed to be used with a transducer type EDO6166, and is taken from an application note of OPA27/37 of Burr-Brown. As you can see, it’s really very simple and uses only conventional components. The transducer used, is piezo type and has a relatively high output impedance, which requires a preamp with a high input impedance. The input impedance of this circuit is mainly determined by the value of the resistor R3, 1 MOhms here. The value of other components determines the frequency range used, it ranges here between 1 kHz and 50 kHz.
