LMC6022
Low Power CMOS Dual Operational Amplifier
General Description
The LMC6022 is a CMOS dual operational amplifier which
can operate from either a single supply or dual supplies. Its
performance features include an input common-mode range
that reaches V−, low input bias current, and voltage gain (into
100k and 5 kΩ loads) that is equal to or better than widely
accepted bipolar equivalents, while the power supply re-
quirement is less than 0.5 mW.
This chip is built with National’s advanced Double-Poly
Silicon-Gate CMOS process.
See the LMC6024 datasheet for a CMOS quad operational
amplifier with these same features.

∴AV ≈ 100 for circuit shown
For good CMRR over temperature, low drift resistors should be used. Matching of R3 to R6 and R4 to R7 affects CMRR. Gain may be adjusted through R2.
CMRR may be adjusted through R7.
