ALC5616-CGT原装音频接口IC 的描述：
The ALC5616is a high performance, low power, stereo channelI2Sinterface audio CODEC.The transmitted data can from analog input or digital microphone input. Also the received data can to headphone output, line output.
The ALC5616features an ultra low power cap-free headphone amplifier.
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 ALC5616continuously monitors the DAC output level. When the powerlevel is low, it increases theinput signal gain to make it sound louder. At the same time, if apeaking signal is detected, itautonomously 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 contains7 independent filters with programmable gain, center frequency and bandwidth to tailor the frequencycharacteristics of embedded speaker system accordingto user preferences. For microphone recording, the DRC in ALC5616can be used as AGC(Auto Gain Controller) to maintain a constant recording volume. Besides, a dynamic wind reduction filter is built in on recordingpath.
The filter can detect the levelof wind noise and on/off dynamically to keep therecording quality.
ALC5616only requires two voltage supplies and consume ultra low power, makingit ideal for mobile devices.
