LMC6042

LMC6042 CMOS Dual Micropower Operational Amplifier August 1999 LMC6042 CMOS Dual Micropower Operational Amplifier General Description 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-powered systems. Other applications for the LMC6042 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 LMC6044 for a quad amplifier with these features.
