Compression Amplifier

GB512/LD512 DATA SHEET

DESCRIPTION

FEATURES

TheGB512andLD512are8pinstand-aloneinputcompression

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.

• 44 dB typical preamplifier gain

• 14 dB typical output stage gain

• compression function ratio 1:1 to 2:1 to ∞:1

• automatic setting of transducer current

• operation down to 1.1 VDC

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.

• greater than 40 dB volume control range

The GB512 and LD512 are recommended for low to medium

gain/output ITE and ITC type hearing aids.

STANDARD PACKAGING

The GB512 is tested to tighter test limits.
