Introduction

Conventional monolithic micropower op amps with a wide supply voltage range require a large die area and, therefore, a large package and footprint. The unconventional LT6011 dual op amp fits 25μV input precision micropower operation and wide 2.7V to 36V supply range in a tiny new package—its 3mm × 3mm DFN package is so small it does not even have leads. The LT6011 also provides rail-to-rail output swing and utilizes superbeta input transistors to achieve picoampere input ...
