SA12-01 Preamplifier, Single-Ended I/O, Phantom Powered

Overview
SensorTech’s preamplifiers have been designed for applications where size and weight are critical but performance cannot be compromised. The SA12-01 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 SA12-01 offers high input impedance and low power consumption.

The SA12-01 has a two-wire single-ended input and output. The SA12-01 is a phantom-powered preamplifier with 25 dB gain.
