TDA8931T  -Power comparator 1 X 20 W

The TDA8931 is a switching power stage for high ef?ciency class-D audio power ampli?er

systems.

It contains a Single-Ended (SE) power stage, drive logic, protection control logic, a full

differential input comparator and a HVP charger to charge the SE capacitor. With this

ampli?er a compact 1 × 20 W closed loop self-oscillating digital ampli?er system can be

built. The TDA8931 has a high ef?ciency so that a heat sink is not required up to

20 W (RMS). The system operates on an asymmetrical and a symmetrical supply voltage.

■ High ef?ciency

■ Operating voltage asymmetrical from 12 V to 35 V

■ Operating voltage symmetrical from ±6 V to ±17.5 V

■ Thermally protected

■ No heat sink required

■ Charger for single-ended capacitor

■ No pop sound
