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 requir-
ing 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.
