LMC6024
Low Power CMOS Quad Operational Amplifier

General Description

The LMC6024 is a CMOS quad 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
100 kΩ and5kΩloads) that is equal to or better than widely
accepted bipolar equivalents, while the power supply re­quirement is less than 1 mW.

This chip is built with National’s advanced Double-Poly
Silicon-Gate CMOS process.

See the LMC6022 datasheet for a CMOS dual operational
amplifier with these same features.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the 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
