Hi team,

I got a question from customer.

I'm looking at making a pet tracker and wanting was looking at your product list: MCU's, audio amps, haptic drives etc.
I was hoping you would be able to help me a little bit to determine which of your products best meet my needs.
Overall: the pet device produces a (one of two) pre-recorded sounds (recorded from the app) and at the same time a haptic effect.
For the MCU I was looking at your: CC2642R and use the BLE to download the voice commands from the app. Also as it has a DAC I wouldn't need an audio codec? If there is a MCU which is better for my needs please let me know.
For the audio amp I was looking at the following:
TPA2010D1
TPA2034D1
TAS2770
OPA1692

Lastly the Haptic driver I was looking at:
DRV2605
However I am not sure whether this haptic driver is overkill as the vibration (actuator: LRA) only needs to be one or two different haptic feels.

Thank you very much for your help.

As I know, you still need codec chip such as TLV320AIC3254 according to SimpleLink Audio Plugin Users Guide.

Hi,

Thank you for reaching out.

First of all, the CC2642R seems to be a good choice here.

When it comes to audio, the CC2642R provides several options. One option would be to use I2S with an external codec (such as TLV320AIC3254). The second option could be to use the DAC with an audio amp. The third option would be to use PWM.

To finish, I would recommend to open two new threads, one dedicated to the Haptic driver and one dedicated tpo the audio amp. This way you will have the proper experts to comments.

Best regards,
