■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.

■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 conventional 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.

■Applications
•Headphone stereo
