CMOS Dual Operational Amplifier
General Description
The LMC662 CMOS Dual operational amplifier is ideal for
operation from a single supply. It 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 V
OS
, drift, and
broadband noise as well as voltage gain into realistic loads
(2 kΩ and 600Ω) are all equal to or better than widely ac-
cepted bipolar equivalents.
This chip is built with National’s advanced Double-Poly
Silicon-Gate CMOS process.
See the LMC660 datasheet for a Quad CMOS operational
amplifier with these same features.
