How To Use The IRS2092S Audio Amplifier IC

The IRS2092S is a class D amplifier building block that combines all of the components of a class D amplifier into a single IC that only requires a few additional components to function. An OTA powers the input stage, which is powered by a +/- supply. On pin 3, this stage performs the major amplification of the input signal. The output is modulated to drive the gates of two N-channel MOSFETs in a half-bridge arrangement using a level shifter. To avoid shoot-through and boost efficiency and decrease distortion, the chip also incorporates overcurrent protection and an adjustable dead-time. The image below depicts a typical application circuit.
