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 reachesV

−

, lowinputbiascurrent, and voltage gain (into
100k and 5 kΩ loads) that is equal to or better than widely
accepted bipolar equivalents, while the power supply re­quirement 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.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to component may occur. Operating Ratings indicate conditions for which the device is in­tended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The
guaranteed specifications apply only for the test conditions listed.

Note 2: Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature and/or multiple Op Amp shorts
can result in exceeding the maximum allowed junction temperature of 150˚C. Output currents in excess of

±

30 mA over long term may adversely affect reliability.

Note 3: The maximum power dissipation is a function of T

J(max)

, θJAand TA. The maximum allowable power dissipation at any ambient temperature is P

D

(T

J(max)

−TA)/θJA.

Note 4: Human body model, 100 pF discharged through a 1.5 kΩ resistor.
Note 5: Typical values represent the most likely parametric norm.
