One stop electronic component supply Original HT3382 2 × 75W Class D stereo audio power amplifier power amplifier ETSSOP28

Product Descriptions

HT3382 is an efficient Class D audio power amplifier.

Under the condition of 24V power supply for stereo sound (BTL) and THD+N=10 percent, it can continuously provide 2 * 75W/4 Ω power output.

Under the condition of 24V power supply PBTL and THD+N=10 percent, it can continuously output 140W/2 Ω power.

HT3382 has advanced spreading function to suppress EMI.

In addition, HT3382 has a built-in shutdown function to minimize standby current, and also integrates functions such as overvoltage protection, DC protection, short circuit protection, thermal protection, and power supply undervoltage abnormal protection, which can comprehensively prevent faults from occurring.
