GENERAL DESCRIPTION
Asynchronous Sample Rate Converter (ASRC) provides independent and asynchronous connections to different processors, such as an application processor, baseband processor or wireless transceiver(BT). Stereo Class-D speaker amplifiers provide 1.5W per channel into 8Ω or 2.8W per channel into 4Ω with a 5V supply, with high THD+N performance, excellent PSRR and low EMI. A mono differential earpiece amplifier is also provided, providing output from any DAC or Analog-in. The ALC5672 features an ultra low power cap-free headphone amplifier. It consumes only less than 5mW power during playback, providing mobile system longer battery life under headphone listening mode. The integrated multi-section DRC(Dynamic Range Controller) and 14-band parametric Equalizer provide further digital sound processing capability of audio playback paths. The multi-section DRC in ALC5672 continuously monitors the DAC output level. When the power level is low, it increases the input signal gain to make it sound louder.
