Portable Digital Audio
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-
cations .
