GENERAL DESCRIPTION
Also the received data can to headphone output, line output. It consumes only less than 6.5mW power during playback, providing mobile system longer battery life under headphone listening mode. The integrated DRC(Dynamic Range Controller) and 7-band parametric Equalizer provide further digital sound processing capability of audio playback paths. The DRC in ALC5616 continuously monitors the DAC output level. When the power level is low, it increases the input signal gain to make it sound louder. At the same time, if a peaking signal is detected, it autonomously reduces the applied gain to avoid hard clipping. It ensures the maximum/consistent signal amplitude without producing audio clipping and speaker damage. The 7-band parametric Equalizer contains 7 independent filters with programmable gain, center frequency and bandwidth to tailor the frequency characteristics of embedded speaker system according to user preferences. For microphone recording, the DRC in ALC5616 can be used as AGC(Auto Gain Controller) to maintain a constant recording volume.
