Gennum -> Semtech
DESCRIPTION
The GS3034 hybrid offers Gennum’s new innovative class H output stage along with two low noise inverting preamplifiers, in a CIC size package.
This new breed of output stage adapts the bias current of the receiver to the users listening environment. In relatively loud environments the receiver will be fully biased similar to a traditional class A amplifier. However, as the loudness of the environment decreases, the bias current of the receiver adjusts to a minimum level required to cleanly pass the signal. At the same time the system maintains adequate “headroom” should the amplitude of the signal suddenly increase. By adapting the bias of the output stage to the requirements of the signal being processed, significant current savings can be realized compared to traditional class A amplifiers.
