Overview

HT326 is a stereo high-efficiency Class D audio amplifier capable of driving speakers up to 50W/4Ω in mono PBTL mode. In stereo BTL mode, it delivers 2×33W/8Ω power output. Its advanced spread-spectrum EMI suppression technology allows EMC requirements to be met using only low-cost ferrite bead filters, reducing overall system cost. The HT326 features comprehensive fault protection, including overvoltage, undervoltage, overtemperature, DC detection, and overcurrent protection, with fault status reporting to the processor to prevent device damage.

Applications

Soundbars
Wireless speakers
Consumer audio applications
TV/monitors
Portable speakers
