Part Number: TLV320AIC3109-Q1
Hi,
I'm designing a PCB using a CC2652 microcontroller and TLV320AIC3109-Q1 codec. I need to use the Codec as a mono audio output so I decided to use the headphone output (instead of adding left and right stereo signals). as the output signal has a maximun sound intensity of 9dB I think I should use an amplifier. Anyone could help me to verify whether the connection between Codec and amplifier is done correctly?
I based my circuit on TLV320AIC3109EVM-K User's Guide . You can see schematic below:
A second question is how should I separate analog and digital ground planes. I've reading that I must separate both planes and join them next to the power supply (a battery) ground pin. Is it correct?
Thank you in advance!
