Part Number: TLV320AIC3204

Hello all,

I think that the input level is different between LINE and MIC.

CC85XX headset reference design 1_3_SCHEMATIC (3).pdf

I want to know the gain set value (register value) of the MIC/LINE input of the TLV 320 AIC 3204.

Could anyone tell me if you know.

Best regards,

Hi, Seishin,

The gain value depends of the kind of configuration. I recommend to go to the Volume Control section of the Analog Input Master. It contains information about the volume control. You will find the default volume that can be configured by the user.

Dear Luis,

I have confirmed the configuration of PPW-Configurator(Volume Control), but I could not find those settings.

CC85xxDK - HEADSET, I think that the input gain differs between MIC and LINE.

I would like to know the setting details of AGC of TLV320AIC3204.

Do you have the script of the specific setting of AGC of TLV320AIC3204?

Best regards,

Seishin

Hi, Seishin,

In order to configure the AGC function, you would require to configure Page 0 / Registers 86-101. These registers contain all the information about the AGC parameters. Could you provide the AGC settings that you require (target gain, max gain, debounce time, etc.)? I can provide a script based on your information.
