Feature

General Description

Wellang Audio AMP solutions provide PWM input audio amplifiers and single hip full digital audio amplifiers with power stage for stereo amplifier system. PWM input audio amplifiers are integrated with high-power full-bridge MOSFET power stages and protection functions such as OCP(Over Current Protection), OTP(Over Temperature Protection), UVP(Under Voltage Protection) and SCP(Short Circuit Protection). These functions protect amplifiers under abnormal conditions.

Full digital audio amplifiers are integrated with versatile digital audio signal processing functions, high-performance, high-fidelity fully digital PWM modulator and high-power full-bridge MOSFET power stages. They receive digital serial audio data with sampling frequencies of 32kHz, 44.1kHz, 48kHz, and 96kHz. They can deliver high watts in stereo mode without heat sink. They have a mixer and Bi-Quad filters which can be used to implement the essential audio signal processing functions like loudness control, compensation of a loud speaker response and parametric equalization.
