Default Good Low-noise op amp?

I want to build some balanced to unbalanced converters for instrumentation. What's a good low-noise / low distortion op amp to use?

Thanks

Mike

Good FET-inpt OP-amps are OPA627 and OPA134 from BurrBrown

Good bipolar OP-amps are OP27/37, AD797

For instrumentation applications -- thermcouple, ultrasound, photodiode, strain bridge -- you really want an instrumentation amplifier from Analog Devices, Linear Tech or Burr Brown (TI), Rather than putting the cart in front of the horse, search by application.

Analog has a 72 page guide to Instrument Amps:

Some of the Burr Brown instrumentation amps show up in good quantity on EBay -- like the INA101, INA103 -- these are pretty expensive if you purchase through a distributor, however.

Excellent. Thank you, both.

This will be a signal conditioner for a sound card.
