Overview

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.
