DESCRIPTION
The GS3013 is a linear hybrid 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.
