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 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
accepted bipolar equivalents.
This chip is built with National’s advanced Double-Poly
Silicon-Gate CMOS process.
See the LMC662 datasheet for a dual CMOS operational
amplifier with these same features.
