CMOS Quad Operational Amplifier
LMC6034 CMOS Quad Operational Amplifier
August 2000
General Description
The LMC6034 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 ground, low input bias current, and high voltage
gain into realistic loads, such as 2 kΩ and 600Ω.
This chip is built with National’s advanced Double-Poly
Silicon-Gate CMOS process.
See the LMC6032 datasheet for a CMOS dual operational
amplifier with these same features. For higher performance
characteristics refer to the LMC660.

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
