HT82V742

Audio PWM Driver

Features

General Description

• Single power supply

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.

• Output Power: 1.5W at 5V and 8Ω load

• Less than 1μA quiescent current

• Wide range input level at 5V

• Bridge-Tied-Load output

• Package types: 8-pin SOP

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.

Applications

• Wide range of audio applications
