ALC5626 datasheet i2s audio dac + headphone and stereo class-ab/d speaker amplifier 18 track id: jatr-1076-21 rev. 1.0 7.10. avc control the automatic volume control (avc) function dynami cally adjusts the input signal quantized by the dac to an expected sound level by setting thmax and thmin. when the average level of input signal quantized by the dac is higher than thmax, the avc will decrease the selected analog gain to attenuate the quantized pulse c ode modulation (pcm) signal to a lower amplitude than thmax. when the average level of input signal quantized by dac is lower than thmin, the avc will increase the selected analog gain to amplify the input si gnal. the quantized pcm signal is then set to a higher amplitude than thmi n. the quantized pcm has an average level between thmin and thmax. in order to avoid outputting a strong am plified signal when the gain detect or input level is transiting from a very small signal to a normal signal, the avc bloc k will limit the selected analog gain to unit gain (=0db) when the input level of the ga in detector is lower than thnonact. figure 13. avc block of dac module figure 14. avc behavior www.datasheet.co.kr datasheet pdf - http://www..net/
