General Description

The APA3541/4 is an integrated class AB stereo

headphone driver contained in an SO-8 or a DIP-8

plastic package with Mute feature . Besides the com-

mon Mute feature , the APA3541/4 further integrates

a voltage divider inside the chip . Thus , the external

resistors can be eliminated . The APA3541 has a fixed

gain of 0dB and the APA3544 has a fixed gain of 6dB

so that external gain setting is unnecessary. The de-

vice is fabricated in a CMOS process and has been

primarily developed for portable digital audio appli-
