Team, does TPA6112A2 have EVM or not? I could not find it in TI store...

If not, could you recommend a headphone amp which can meet below requirement?

1. Has EVM available on TI store

2. drive 2*100mW at 16ohm.

3. Adjustable gain setting. (Higher than 4dB, TPA6130 only has 4dB gain)

Hi Nic,

Unfortunately non of the TPA611xA2 devices have EVM available.
We try to promote DirectPath devices as these are newer devices. Also TPA6130A2/TPA6133A2 is the device with highest output power of this family. There are other devices with higher gain settings, but lower output power.

Looks like no devices can meet these requirement...

BTW, could you look at this thread again, I have new post: e2e.ti.com/.../784756

Nic,

Don't know what are the supply requirements, perhaps you could consider TPA6120A2 or SoundPlus devices from OPA16x2 family: www.ti.com/.../soundplus.html
These devices set its gain based on input/feedback resistors, and its output capabilities mostly depend on its supply voltage.
