DESCRIPTION The MT6832 is a 3W, filterless, single-ended input, stereo class-D audio amplifier. It is low noise, filter-free with PWM architecture, minimizing external component count, PCB area, system cost. The chip features very low 0.07% THD+N, high 90dB SNR, and therefore offer high quality sound. MT6832 delivers up to 3W per channel into a 4Ω load with an efficiency up to 90%. The MT6832 features a low-power consumption shutdown mode. The gain of the MT6832 is externally configurable which allows independent gain control from multiple sources by summing the signals. 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 MT6832 an ideal choice for both battery-powered speakers and portable devices. FEATURES 3W output at 10% THD with a 4Ω load and 5V power supply 2.5V~5.5V single supply operation Filterless, low quiescent current and low EMI Less than 0.07% THD+N Low quiescent current and low-power shutdown current Few external components to save the space and cost Over current/Short circuit and over temperature protection Available in SOP16 package (Pb-free) APPLICATION Mobile phone Portable audio product Portable media player Personal navigation device Video game Cordless phone
