SA04 -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 SA04 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 SA04 offers high input impedance and low-power consumption.

The SA04 has a two-wire single-ended input and output. The SA04 is a phantom-powered preamplifier with 30 dB gain.
