FEATURES

鈥?44 dB typical preamplifier gain

鈥?14 dB typical output stage gain

鈥?compression function ratio 1:1 to 2:1 to

鈭?/div>

鈥?automatic setting of transducer current

鈥?operation down to 1.1 VDC

鈥?greater than 40 dB volume control range

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

鈩?/div>

to 5 k鈩?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.
