The LMC660AIN/NOPB is a CMOS quad Operational Amplifier ideal for operation from a single supply. It operates from +5 to +15.5V and features rail-to-rail output swing in addition to an input common-mode range that includes ground. Performance limitations that have plagued CMOS amplifier in the past are not a problem with this design. Input VOS, drift and broadband noise as well as voltage gain into realistic loads (2kR and 600R) 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.
