LMC662 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 VOS, drift, and broadband noise as well as voltage gain into realistic loads (2 k and 600) 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 LMC660 datasheet for a Quad CMOS operational amplifier with these same features.
