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.
