  2nd half.

  There are better options than the OP-275, based on listening test, rather than mere spec sheet info.

  My favorite (still) for less than the all out $20 apiece op-amps is the Burr-Brown OPA-2604 (604 single), available from Digi-Key.

  It has very low distortion, and a fast slew rate. So if the price is right go for it!!!

  • Can Analog Devices OP275 directly replace current OP ? ( NE5532N / TL072CP) dgrambo 16:00:53 02/23/00 (2)

    Can you tell from the info if the AD OP275 is a direct swap?
    If the pinouts match, can I assume the voltage and architecture match?

      You can change it without fear. But I recommend you rather to use AD826 which is much faster and better sounding. Can oscilate in some circuits with pure power supply, so I recomment to bypass some smaller Balck Gates (10uF will be fine) on PS near op-amp. Still, you can use OPA2604 for direct 5532 substitution (sweeter sounding as AD826, but not so fast - depends on taste).

      Enjoy!

      My design partner is a senior application engineer for the Power MOS-FET Division of Siemens Components. He currently is in Munich, he returns to the U.S. this weekend. Monday, I can have him to do a search of the Siemens data base, for cross references for the parts you list. I'll post the info no later than tuesday. This way there will be NO risk regarding the proper replacement.
