We are attempting to find a TI solution to power our inverted supply on two LME49724, two OP1656, and two BUF634A.
The role of the LME49724 is an analog ADC input buffer, the OPA1656 and BUF634A are a DAC line out stage / and headphone amp.
We simply can't get the ADP5074 to work and regret not taking the time to find a TI solution; as these are the only things that ever seem to work for us.
Our power supply input is 12V switched supply and we're attempting to provide a +/-12V to our op amps. We're hoping to find a quiet solution for audio applications.
