One stop electronic component supply Original HT326 inductance free filtering 2 × 30W Class D Stereo Audio Amplifier chip ESOP16

Product Descriptions

HT326 is a stereo efficient, Class-D audio amplifier for driving speakers up to 50W/4 Ω in mono PBTL. It can also deliver 2×33W/8Ω power in stereo BTL.

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

HT326 is fully protected against faults with Overvoltage, Undervoltage, Overtemperature, DC-detect, and Overcurrent protection. Faults can be reported to the processor to prevent devices from being damaged.
