IR4321 Product details

Description

The IR43x1 integrates 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 IR43X1operates without mechanical heatsink attached in a typical music playback usage.

Features

Integrated analog input Class D audio amplifier in a small 5 x 6 mm PQFN package.
High peak music power output.
No mechanical heatsink required.
Split or single power supply.
Differential or single-ended input.
Over-current, over-temperature and under voltage protections with self-reset function.
Start and stop click noise reduction.
High noise immunity.
RoHS compliant Typical.
