Audio signal processing IC for 1.5 V headphone stereo
1
I
Overview
The AN7500FHQ is a single chip IC optimum for a
1.5 V headphone stereo system including pre-amp., power
amp. and Dolby B type noise reduction circuit. Current
consumption in a Dolby circuit off mode has been drasti-
cally reduced and an operating supply voltage has also
been lowered to 0.98 V. Much fewer external components
have been realized due to an integration of audio signal
processing system into a single chip circuitry in a small
outline package and space saving mounting of a set.
I
Features
Reduction by power consumption of approximately 35%
as compared with conventional products, contributing
to low power consumption of a set.
Eliminating the DC/DC converter so far needed for con-
ventional system due to 1.5 V single power supply, and
reducing approx. 40% of external components. This
contributes to space saving in a set.
Built-in standby switch to reduce consumption current
considerably.
