How To Use The IRS2092S Audio Amplifier IC
The IRS2092S is a class D amplifier building block that integrates all the different elements of a class D amplifier into one IC, requiring only a few external components to work. The input stage consists of an OTA, which is powered by a +/- supply. This stage carries out the main amplification of the input signal on pin 3. The output is passed on to a level shifter and modulated to drive the gates of two N-channel MOSFETs in a half-bridge configuration. The chip also has overcurrent protection and an adjustable dead-time to prevent shoot-through and increase efficiency and reduce distortion. The typical application circuit is shown in the figure below.
Applications
- Home theatre systems
- Mini component stereo systems
- Powered speaker systems
- General-purpose audio power amplifiers
