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 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.
This chip is built with TI's advanced Double-Poly
Silicon-Gate CMOS process.
See the LMC660 datasheet for a Quad CMOS
operational amplifier with these same features.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
