LMC660
CMOS Quad Operational Amplifier
General 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. Perfor-
mance 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 k⦠and 600â¦) are all equal to or better than widely
accepted bipolar equivalents.
This chip is built with Nationalâs advanced Double-Poly
Silicon-Gate CMOS process.
See the LMC662 datasheet for a dual CMOS operational
amplifier with these same features.
