TLV320AIC3007: About the fade-in / fade-out setting of TLV320AIC3007

Part Number: TLV320AIC3007

Hello,

I would like to set fade-in / fade-out on the TLV320AIC3007.

Could you tell me how to set the registers and timing?

Best regards,
Nomu

  • Hello Nomu,

    By Fade-in/Fade-out, are you referring to the AGC function or volume control? We don't have a fade-in/fade-out function for our volume control but we do have a soft-stepping feature that is used to help ramp changes in gain to help with pops/clicks. If you wish to use soft-stepping, you can use register 19 to control the left PGA and register 22 to control the right PGA soft stepping. Register 40 can be used to configure soft stepping for the output volume. 

    Regards,
