TLV320DAC3203: Is it possible to adjust delay of headphone amplifiers output?

Hi Yaita-san,

The default setting is "H(z) = 1", but it is changed to "H(z) = Z^-1" if applying the following coefficients to the biquad filter.
So, "Z^-1" means the 1/fs delay.

N0 = 0
N1 = 2^22
N2 = 0
D1 = 0
D2 = 0

In the same way as above, it is changed to "H(z) = Z^-2" if applying the following coefficients to the biquad filter.

N0 = 0
N1 = 0
N2 = 2^23
D1 = 0
D2 = 0

Hi, Yaita-san,

In addition to the biquad filter delay, you must consider that each decimation filter has its own delay as shown below:

- Decimation filter A: 17 / fs.
- Decimation filter B: 11 / fs.
- Decimation filter C: 11 / fs.
