Hi Raymond, Do you have a reference design for the OPA1656 using a single +12v Supply?

What is your specific audio application? For OPA1656 with a single 12V supply rail, you have to bias the op amp properly. Here is an example.

Please let me if you have other questions.

Will this reference apply also to OPA1602 or it would be different?

Yes, it should work. I would change Vbias voltage to 6Vdc or the mid point of 12Vdc supply for OPA1602, because OPA1602 is close to be RRO, rail to rail output (not RRI). 

If you have other questions. please let us know. 

Best,
