One quick question.
Could I replace LT1028 used in analog output stage with virtually any similar opamp.
I have a few opa2604, opa2134, opa627 or ad797, ad8001.

??????????????????
I thought it would be very simple (not for me). Is it so simple nobody wants to answer ?

When you show the circuit someone will be able to answer. It's like asking which boat is best to cross the water. Which water ? Ocean or lake ?
You see ? So what circuit / which cdplayer/ what rail voltages etc.

Since he is refering to a DAC which isn't released yet I think he means the circuit in the datasheet

Opamp question. The filter should be low noise and low distortion if you really want to take advantage of the high performance of the DAC.
See also my wonderings about the weird opamp choices in the datasheet in on eof the threads above.
