Ultra-low power consumption and low input-leakage
current are the hallmarks of the LMC6042. Providing
input currents of only 2 fA typical, the LMC6042 can
operate from a single supply, has output swing
extending to each supply rail, and an input voltage
range that includes ground.
The LMC6042 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-
Other applications for the LMC6042 include bar code
reader amplifiers, magnetic and electric field
detectors, and hand-held electrometers.
This device is built with TI's advanced Double-Poly
Silicon-Gate CMOS process.
See the LMC6041 for a single, and the LMC6044 for
a quad amplifier with these features.
