LMC6044 CMOS Quad Micropower Operational Amplifier
Check for Samples: LMC6044
FEATURES
1
2 Low Supply Current: 10 μA/Amp (Typ)
• Operates from 4.5V to 15.5V Single Supply
• Ultra Low Input Current: 2 fA (Typ)
• Rail-to-Rail Output Swing
• Input Common-Mode Range Includes Ground
APPLICATIONS
• Battery Monitoring and Power Conditioning
• Photodiode and Infrared Detector Preamplifier
• Silicon Based Transducer Systems
• Hand-Held Analytic Instruments
• pH Probe Buffer Amplifier
• Fire and Smoke Detection Systems
• Charge Amplifier for Piezoelectric Transducers
DESCRIPTION
Ultra-low power consumption and low input-leakage current are the hallmarks of the LMC6044. Providing input
currents of only 2 fA typical, the LMC6044 can operate from a single supply, has output swing extending to each
supply rail, and an input voltage range that includes ground.
The LMC6044 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 LMC6044 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 LMC6041 for a single, and the LMC6042 for a dual amplifier with these features.

Instrumentation Amplifier
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Absolute Maximum Ratings indicate limts beyond which damage to the device 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.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3) Do not connect output to V+ when V+ is greater than 13V or reliability may be adversely affected.
(4) 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.
(5) The maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any ambient
temperature is PD = (TJ(max) TA)/θJA.
(6) Human body model, 1.5 kΩ in series with 100 pF.
