Preliminary

RT9131

Class AB Stereo Headphone Drive with Mute

General Description

Features

ꢁ High Signal-to-Noise Ratio

The RT9131 is an integrated class AB stereo

headphone driver contained in a SOP-8 or DIP-8

plastic package with Mute feature. A class AB output

stage bias control circuit is employed to maintain low

audio signal distortion and power consumption. The

RT9131 further integrates a voltage divider inside

the chip. Thus, the external resistors can be

eliminated. The device is fabricated in a CMOS

process and has been primarily developed for

portable digital audio applications.
