General Description
The APA4801 is an integrated class AB stereo headphone amplifier contained in an SO-8 or a DIP-8 plastic package with Mute feature . Besides the common Mute feature , the APA4801 further integrates a voltage divider inside the chip . Thus , the external resistors can be eliminated . The device has been primarily developed for portable digital audio applications .
