General Description

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.

Key Features

  • ×30W (VDD=16V, RL=4Ω, THD+N=10%, Class D or Class AB) 2×18W (VDD=12V, RL=4Ω, THD+N=10%, Class D or Class AB).
  • Single Wide Voltage Supply: 3V-18V.
  • Low Quiescent Current: 14mA (VDD = 12V, with LC and Load, Class D).
  • Anti-clipping Function (ACF).
  • Spread Switching Frequency, Inductor-free Operation.
  • Differential / Single-ended Analog Input.
  • Integrated Self-protection Circuits Including, Undervoltage, Overtemperature, and Overcurrent.
  • LF and HF Package of ETSSOP28, EPAD up.
