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.
●High efficiency
●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
