LMC662 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 kW and 600W) 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.
