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
to 5 k without adding any external
resistors to set the bias.
The GB512 and LD512 are recommended for low to medium
gain/output ITE and ITC type hearing aids.
The GB512 is tested to tighter test limits.
