Hi Chris,

Welcome to e2e.
I'll look for the TPA6120A2 symbol, what package are you using? Is it DWP?
I think I don't get you question about OPA4314. You can use OPA4134 between DAC and TPA6120A2, actually this is the typical application shown in TPA6120A2 datasheet page 9.

thank you for your answer, i want to use VQFN-14 package, and yes i will go ahead for OPA4134 as typical application shown in TPA6120A2
