TECHNICAL NOTE

Sound Path Selector IC Series for Mobile Phones

Mixer & Selector

with PCM CODEC

and 16bit D/A Converter

BU7861KN

●Abstract

The “In/Output Selector with Built-in PCM Codec 16bit D/A Converter” LSI is ideal for improving the sound quality of and

miniaturizing cellular phone handsets with music playback function, accumulating analog circuits for sound which

application CPUs and bass band LSIs are not ideally able to handle.

●Features

1) Loaded with stereo 16bit audio D/A converter

2) Compatible with stereo and analog interfaces

3) Built-in stereo headphone amp (16Ω)

4) Lowpass correction circuit built into the headphone amp

5) Gain-adjustable volume built in

6) Flexible mixing function built in

●Uses

Portable information communication devices such as cellular phone handsets and PDA (Personal Digital Assistants)

Cellular phone handsets with music playback function
