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.

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.
