Hi,
We have the following queries:
1. TLV320AIC3105:
We are using the TI audio codec, AIC3105 in one of our boards. We are observing a significant attenuation in the frequency response of the codec below 200Hz and also at the high end around 18KHz. Please let us know if the codec has a flat frequency response over the audio frequency range (20Hz – 20KHz).
2. TLV320AIC34:
We have the following queries regarding the AIC34 codec.
- Each block of the codec (A or B) has two mic inputs and one microphone detect (MICDET). How can we connect this MICDET to both the mic inputs?
- Can we use the line outputs of the codec in single ended mode? If so, do we need to ground the negative input or can we leave it no connected?
- We need to interface the line outputs to 3.5mm stereo jacks in single ended mode. In that case what is the ac coupling capacitor that has to be used to connect the line outs to stereo jacks?
- Does the codec support jack/headset detection on line outputs?
Regards,
Gitesh
