WebThe op amp is the heart of the circuit. The OPA1642 has really low noise, low distortion, and high bandwidth. That gives us a flat buffer amplifier, probably good to a megahertz. … Web28 dec. 2024 · where is the open-circuit receiving voltage sensitivity of the hydrophone and is the transmit current response of reciprocal transducer X. Unlike the free-field form of this expression, there is no dependence on separation distances, and the transmit current response is the pressure inside the cavity for a given current—there is no reference …
