3W unfiltered D-class monaural audio amplifier chip
3W single channel unfiltered D-class audio amplifier chip, with excellent EMI and noise suppression capabilities, specific output power and distortion, high efficiency, high PSRR, low static current, and multiple protection functions, suitable for handheld devices such as mobile phones, and packaged in SOP8
3W unfiltered D-class stereo audio amplifier chip
A stereo D-class audio power amplifier can provide the performance of an AB class power amplifier with the efficiency of a D-class amplifier. Adopting a low-noise, filter free structure saves PCB space and system costs, with system shutdown and mute control functions. The special circuit architecture enhances noise resistance and reduces RF interference.
3W anti loss stereo D-class audio amplifier chip
A Class D audio power amplifier with anti distortion function and ultra-low EMI stereo output free filter. Under the conditions of 5V power supply, 4 Ω load, and THD+N=10%, it outputs 3W power with performance comparable to AB class amplifiers and an efficiency of up to 88%. It can detect and suppress distortion caused by excessive input signal amplitude or reduced power supply voltage. The sound quality and power are set by external resistors and capacitors, and unique EMI suppression technology is used. It integrates filter free digital modulation technology and has multiple protection functions. It is packaged in lead-free SOP16.
