The TP5228 is an integrated class AB stereo headphone driver contained in an
SO-8 or a DIP-8 plastic package with Mute feature.The TP5228 operates in low power
mode to reduce supply current to 600
A
and keep no switch ON/OFF clicks. Besides
the common Mute feature, the TP5228 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.
