HT3166 Overview
HT3166 is a stereo efficient, Class AB/D audio amplifier. In class D mode, the device can drive a speaker up to 2×40W/4 Ω at VDD = 18V, In class AB mode, the device can drive a speaker up to 2×30W/4 Ω at VDD = 16V, with a small heat-sink attached to its top side EPAD. Advanced EMI Suppression enables the use of inexpensive ferrite bead filters while meeting EMC requirements for system cost reduction in Class D mode.
