Hi Justin

We do have newer components like the OPA1679-Q1 a quad lower cost audio amp which is going to be released to production very soon. However, for the OPA1612-Q1 we don't have anything that can give you better performance. What is the application and what are you looking to do?

Hi Justin

Thank you. The parts you are looking at some of the highest performance we have in the portfolio for audio.

One worth mentioning for premium sound systems is the INA1650-Q1 which is a differential line receiver with superior EMI performance and noise cancellation.

As I mentioned earlier, the OPA1679-Q1, a quad cost optimized audio amplifier, could be very useful to you as a general purpose op amp in your board, it is releasing to production in the next 2 weeks.
