FEATURES
DESCRIPTION
The LMC660 CMOS Quad operational amplifier is
ideal for operation from a single supply. It operates
from +5V to +15.5V 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 VOS, drift, and
broadband noise as well as voltage gain into realistic
loads (2 kΩ and 600Ω) are all equal to or better than
widely accepted bipolar equivalents.
