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.
