The item previously listed is the DIP version. You probably need the soic version.

Search result for: 5872015 - Future Electronics Ask if it's available in smaller quantities.

STMICROELECTRONICS | TL072CDT | TL072 Series SOP8 High Speed Low Noise JFET Dual Operational Amplifier - Future Electronics

Try Digikey. Looks like they might have the LM211

On most boards, all the ones listed are defaced.
