LMC6034
CMOS Quad Operational Amplifier

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

±

30 mA over long term may adversely affect reliability.

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

J(max)

, θJA,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.
Note 6: All limits are guaranteed at room temperature (standard type face) or at operating temperature extremes (bold type face).
