The combination of an advanced audio controller IC with MOSFETs fully optimised for audio performance results in improved efficiency, THD, and EMI, allowing the IR43xxM family to operate without a mechanical heatsink over a wide power supply range on either a single or split power supply. High voltage ratings and noise immunity ensure reliable operation over various environmental conditions.
The single channel IR4301M and dual channel IR4302M offer the flexibility and convenience of building stereo amplifier and multi-channel designs in various channel configurations, while the devices’ 5×6 mm and 7×7 mm PQFN packages enhance the benefit of utilizing a smaller size of Class D topology.
Other key features common to the family include over-current protection, thermal shutdown, internal/external shutdown and floating differential input. The IR4302M also offers clip detection.
A wide range of reference designs are available to further simplify the design of systems using these devices.
