3 Description

The dual LMC662 and quad LMC660 (LMC66x) are

CMOS operational amplifiers designed for operation

from a single supply, and built with TI's advanced

CMOS process. The device operates from 5V to 15V

and features rail-to-rail output swing in addition to

an input common-mode range that includes ground.

Performance limitations that have plagued CMOS

amplifiers in the past are not a problem with this

design. Input offset voltage (VOS), offset drift, and

broadband noise as well as voltage gain into realistic

loads (2kΩ and 600Ω) are all equal to or better than

widely accepted bipolar equivalents.
