Linear Class H Amplifier

GC590 - DATA SHEET

DESCRIPTION

The GC590 is a linear amplifier system containing three

amplifier stages.

This product incorporates a current mode class H power

amplifier.

By adapting the bias of the output stage to the requirements

of the signal being processed, significant current savings

can be realised compared to traditional class A amplifiers.

The adaptive action does not compromise the characteristics

of a current drive output stage.

In addition to the output stage, two additional stages of

preamplification are provided to allow filtering and gain

adjustment to be easily accomplished.
