HT82V742

Audio PWM Driver

General Information

The HT82V742 is an audio PWM driver IC which can directly drive speakers. The device can deliver up to 1.5 watts into an 8Ω load with a 5V operating voltage. The advantage of using an audio PWM driver is that any general purpose MCU, for example the HT32F series, in being able to generate PWM outputs can therefore have voice functions.

One special feature of the device is its ability to operate on a single power supply 5V with wide range input level. The superior efficiency of this Holtek audio PWM driver together with its wide operating voltage and ability to directly driver speakers make it excellent for use in a wide range of voice applications.
