LMC6061
Precision CMOS Single Micropower Operational
Amplifier
General Description
The LMC6061 is a precision single low offset voltage, micropower 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 includes ground.These features, plus its low power consumption, make the LMC6061 ideally suited for battery powered
applications.
Other applications using the LMC6061 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 LMC6081
precision single operational amplifier.
For a dual or quad operational amplifier with similar features,
see the LMC6062 or LMC6064 respectively.

AC Electrical Characteristics (Continued)
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 shortcircuitoperationatelevatedambienttemperaturecan 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, and TA. The maximum allowable power dissipation at any ambient temperature is P
D
=
(T
J(Max)
−TA)/θJA.
Note 4: Human body model, 1.5 kΩ in series with 100 pF.
Note 5: Typical values represent the most likely parametric norm.
Note 6: All limits are guaranteed by testing or statistical analysis.

Note 8: V
+
=
15V. Connected as Voltage Follower with 10V step input. Number specified is the slower of the positive and negative slew rates.
Note 9: For operating at elevated temperatures the device must be derated based on the thermal resistance θ

with P
D
=
(T
J–TA
)/θJA.
Note 10: Do not connect output to V
+
, when V+is greater than 13V or reliability witll be adversely affected.
Note 11: All numbers apply for packages soldered directly into a PC board.
Note 12: For guaranteed Military Temperature Range parameters see RETSMC6061X.
