One stop electronic component supply Original HT313 20W mono D-class audio amplifier chip ESSOP10

Product Descriptions

HT313 is a mono efficient, Class-D audio amplifier for driving speakers up to 23W/2 Ω, THD+N=1% at PVDD = 12V. 

Advanced EMI Suppression with Spread Spectrum Control enables the use of inexpensive ferrite bead filters while meeting EMC requirements for system cost reduction. 

The built-in shutdown function of HT313 minimizes the standby current. HT313 is fully protected against faults with Overvoltage, Undervoltage, Overtemperature, DC-detect, and Overcurrent protection.
