TDA8931 Power comparator 1 × 20 W Rev. 01 — 14 January 2004 Preliminary data sheet 1. General description The TDA8931 is a switching power stage for high efficiency class-D audio power amplifier 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 amplifier a compact 1 × 20 W closed loop self-oscillating digital amplifier system can be built. The TDA8931 has a high efficiency so that a heat sink is not required up to 20 W (RMS). The system operates on an asymmetrical and a symmetrical supply voltage. 2. Features s s s s s s s High efficiency Operating voltage asymmetrical from 12 V to 35 V Operating voltage symmetrical from ±6 V to ±17.
