Op-amps? 347 options to pick from...! Many of our original op-amps have become industry standards. Like OP-05, OP-07, OP-27. But we have more — the industry's widest choice. From 35 basic models, various electrical grades and package styles, we derive a total of 347 versions. Not even counting dice, which we offer too. We have — almost — every type: General purpose, precision, low input current, micropower, programmable, high speed, high load; singles, duals, quads; military, industrial, commercial temperature range; 883 and JAN qualified parts.
