General Description

The GB512 and LD512 are 8 pin stand-alone input compression amplifiers requiring minimal external parts.

Each consists of a voltage regulator for the electret microphone providing a high power supply rejection ratio (PSRR), a compression stage which has a 2:1 compression ratio, and an auto-biasing, class A, voltage drive output stage.

The auto-bias output stage can drive a variety of impedances ranging from 500 Ω to 5 kΩ without adding any external resistors to set the bias.
