General Description
The APA4801 is an integrated class AB stereo head-
phone amplifier contained in an SO-8 or a DIP-8 plas-
tic package with Mute feature . Besides the common
Mute feature , the APA4801 further integrates a volt-
age divider inside the chip . Thus , the external resis-
tors can be eliminated . The device has been prima-
rily developed for portable digital audio applications .
