IR4312 - 2-Channel Integrated Analog Input Class D Audio Amplifier

Download the IR4312 datasheet PDF. This datasheet also covers the IR4302 variant, as both devices belong to the same 2-channel integrated analog input class d audio amplifier family and are provided as variant models within a single manufacturer datasheet.

General Description

The IR43x2 integrates 2 channel PWM controller and digital audio MOSFETs forming a high performance Class D audio amplifier.

As a result of fully optimized MOSFETs co-packed with a dedicated controller IC, the IR43X2 operates without mechanical heatsink attached in a typical music playback usage.

Key Features

  • 2 channel integrated analog input Class D audio amplifier in a small 7 x 7 mm PQFN44 package.
  • No mechanical heatsink required.
  • High peak music power output.
  • Split or single power supply.
  • Differential or single-ended input.
  • Over-current, over-temperature and under voltage protections with self-reset feature.
  • Start/stop click noise reduction.
  • Clip and Fault reporting outputs.
  • High noise immunity.
  • RoHS compliant Typical.
