MT6823

  MT6823 3W Filterless Ultra-low EMI Stereo Class-D Audio Amplifier with DC Volume Control DESCRIPTION The MT6823 is a 3W, filterless, ultra-low EMI noise, fully differential input, stereo class-D audio amplifier, which provides precise DC volume control from 24dB to -24dB with 30 steps. It is low noise, filter-free with PWM architecture, minimizing external component count, PCB area, system cost. The chip features very low 0.1% THD+N, high 90dB SNR, and therefore offer high quality sound. MT6823 delivers up to 3W per channel into a 4Ω load with an efficiency up to 90%. The MT6823 features a low-power consumption shutdown mode. Output short circuit and thermal overload protection prevent the device from damage during fault conditions The high efficiency and a low shutdown current make the MT6823 an ideal choice for both battery-powered speakers and portable devices. MT6823 integrates Maxic’s unique EMI suppression technique, can work with FM tuner without extra Ferrite-bead compo...
