LMC6041
CMOS Single Micropower Operational Amplifier
General Description
Ultra-low power consumption and low input-leakage current
are the hallmarks of the LMC6041. Providing input currents
of only 2 fA typical, the LMC6041 can operate from a single
supply, has output swing extending to each supply rail, and
an input voltage range that includes ground.
The LMC6041 is ideal for use in systems requiring ultra-low
power consumption. In addition, the insensitivity to latch-up,
high output drive, and output swing to ground without requiring external pull-down resistors make it ideal for
single-supply battery-powered systems.
Other applications for the LMC6041 include bar code reader
amplifiers, magnetic and electric field detectors, and
hand-held electrometers.
This device is built with National’s advanced Double-Poly
Silicon-Gate CMOS process.
See the LMC6042 for a dual, and the LMC6044 for a quad
amplifier with these features.

AC Electrical Characteristics (Continued)
Note 1: AbsoluteMaximum Ratings indicate limits beyond which damage to the device may occur. Operating conditions 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 can result in exceeding the
maximum allowed junction temperature of 110˚C. Output currents in excess of
±
30 mA over long term may adversely affect reliability.
Note 3: Themaximum 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 at room temperature (standard type face) or at operating temperature extremes (bold face type).
Note 7: V

connected to 7.5V. For Sourcing tests, 7.5V ≤ VO≤ 11.5V. For Sinking tests, 2.5V ≤ VO≤ 7.5V.
Note 8: V
+
=
15V. Connected as Voltage Follower with 10V step input. Number specified in 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
JA
with P
D
=
(T
J−TA
)/θJA.
Note 10: All numbers apply for packages soldered directly into a PC board.
Note 11: Do not connect output to V
+
when V+is greater than 13V or reliability may be adversely affected.
