The EVM is the TPA2012D2EVM . You can find it in the "Hardware Development" tab on the TPA2012 product page. The EVM has documentation for its layout and schematics.

I have tried with TPA2012D2EVM. Current consumption is lower after short at the output, similar to having the amplifier in shutdown mode. Device current consumption is normal after cycling SHUTDOWN pin to take the device back to active mode…
I used the TPA2012D2EVM to perform the test. I configured the EVM based in the User's guide under the following conditions: Vdd=5V, Gain= 16V/V, differential inputs, RL=8Ω in each output and Vin=0.5Vrms. I mentioned to you the behavior previously…
What MEMS mic are you thinking of using? MEMS microphones can behave like traditional electret analog microphones with an integrated DAC to output a small amplitude signal. Or they can be a digital microphone - outputting a PDM stream of 1's…
Hi V Pot,
Actually, the AIC3206 onthe C5545 BoosterPack has a built in charge pump specifically for the headphone output. This allows the headphone jack to output a slightly higher 5.8-mW without the large DC blocking caps and with the same 1.8V supply…
Thank you for the advice.
Just managed to got hold of TPA2012D2EVM. Seems like the IC used in the evm is WSCP instead of QFN which I've decided to use. Is there any QFN evm around since my spec is 2.1W/ch
