SA03 - Preamplifier, Differential I/O

Overview
SensorTech’s preamplifiers have been designed for applications where size and weight are critical but performance cannot be compromised. The SA03 is ideal for use with piezoelectric sensors such as hydrophones and vibration detectors but can also be used in other applications. Surface-mount technology provides small size, yet, reliable low-noise configuration. The SA03 offers high input impedance and low power consumption.

The SA03 has a differential input and output. The SA03 comes standard with a 40dB gain, however, the gain can be tailored to fit customer specifications.
