Description

The LC552 is a versatile low voltage, high gain, high power output amplifier.

It features a preamplifier module with adjustable gain and a unique power amplifier module that can be operated either as a high power, high efficiency class B amplifier, with very low quiescent current consumption, or as a medium power "vari-bias" class A amplifier.

While designed specifically for use in body type hearing aids, the LC552 can be used in other applications where linear audio frequency amplification and frequency shaping is required.
