DESCRIPTION The GB512 and LD512 are 8 pin stand-alone input pression amplifiers requiring minimal external parts. Each consists of a voltage regulator for the electret microphone providing a high power supply rejection ratio (PSRR), a pression stage which has a 2:1 pression ratio, and an auto-biasing, class A, voltage drive output stage. The auto-bias output stage can...
