TDA8931 Power comparator 1 × 20 W

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.
