HT337B - 120W Class D Mono Amplifier

General Description

HT337B is a mono efficient, Class D audio amplifier.

The device can drive a speaker up to 120W/4 Ω at VDD = 30V.

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

Key Features

  • S Output Power 120W (VDD=30V, RL=4Ω, THD+N=10%) 76W (VDD=32V, RL=8Ω, THD+N=10%) Single Wide Voltage Supply: 4V-30V Low Quiescent Current: 10mA (VDD = 24V, with LC and Load) Anti-clipping Function (ACF) Power Limit (PLIMT) function that can be used to clip the output voltage level below the supply rail Spread Switching Frequency, Inductor-free Operation Differential / Single-ended Analog Input Integrated Self-protection Circuits Including, Undervoltage, Overtemperature, and Overcurrent LF and HF.
