SA09 -Preamplifier, Single-ended I/O, Low Power Consumption

Overview
SensorTech’s preamplifiers have been designed for applications where size and weight are critical but performance cannot be compromised. The SA09 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 and reliable low-noise configuration. The SA09 offers high input impedance and low-power consumption.

The SA09 has a single-ended input and output. The SA09 is a voltage follower.
