Tool/software:
Hi all,
I would like to ask about the frequency parameter of the voice through TLV320AIC1110.
For both boards mounting TLV320AIC1110,
・TX gain:29.5dB
・RX gain:-4dB
setting, if you look at the frequency response of the input and output,
will it be 25.5dB (29.5dB-4 dB)?
(In the range of 300 Hz to 3400 Hz.)
If not, could you please tell us the reason?
*This time, using an external circuit, the calculation shows 0dB.
The measurement shows -4dB (around 1 kHz).
We are investigating why the calculation deviates so much.
As for the external circuit, the AC analysis of LTSpice and the calculation almost agree.
We are checking if we missed something in the characteristics of TLV320AIC1110.
Best Regards,
Ryusuke
