General Description

The HT82V736 is a class AB stereo earphone driver designed for portable digital audio application. It provides an integrated mute function to prevent popping sounds when power is turned on and off. In addition, the HT82V736 further integrates a voltage divider, and therefore the external resistors can be eliminated. The HT82V736 has a fixed gain of 6dB so that external gain setting is unnecessary. It is fully pin and functionally compatible with BH3544 which is suitable for effective low cost applications.
