TLV320AIC3105 datasheet

Other Parts Discussed in Thread: TLV320AIC3105

Hi,

A customer has two questions about TLV320AIC3105 datasheet.
Q1. Page 0/Register 20: LINE2L to Left ADC Control Register seems not to affect the gain of the path from LINE2L to HPROUT.
So, he does not know whether the Functional Block Diagram in page 18 is correct.

Q2. He thinks that the table 66, 68 and 69 of TLV320AIC3105 datasheet (SLAS513C) must be typographical errors.
He wants to know error free contents of these table.

Best regards,
Akio Ito

    Hi, Ito-san,

    1. Page 0 / Register 20 is used to configure the gain from the LINE2L to the left-ADC. It won't affect the gain from LINE2L to HPROUT because this gain is applied on the ADC operations. If you're looking to configure the path from LINE2 to HPROUT, you would need to configure Page 0 / Register 40 for bypass path control (bits D2 - D5).

    2. That's correct. There are some typo errors in tables 66, 68 and 69 that must be modified. Please take a look at the following document for the correct values.
