LMC6062
Precision CMOS Dual Micropower Operational Amplifier
General Description
The LMC6062 is a precision dual low offset voltage, mi-
cropower operational amplifier, capable of precision single
supply operation. Performance characteristics include ultra
low input bias current, high voltage gain, rail-to-rail output
swing, and an input common mode voltage range that in-
cludes ground. These features, plus its low power consump-
tion, make the LMC6062 ideally suited for battery powered
applications.
Other applications using the LMC6062 include precision
full-wave rectifiers, integrators, references, sample-and-hold
circuits, and true instrumentation amplifiers.
This device is built with National's advanced double-Poly
Silicon-Gate CMOS process.
For designs that require higher speed, see the LMC6082
precision dual operational amplifier.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended 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. Continous short circuit operation at elevated ambient temperature can result in exceeding the maxi-
mum allowed junction temperature of 150C. 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)
,
