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.
