Features Low supply current: 10 µA/Amp (Typ) Operates from 4.5V to 15.5V single supply Ultra low input current: 2 fA (Typ) Rail-to-rail output swing Input common-mode range includes ground 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. Applications Battery monitoring and power conditioning Photodiode and infrared detector preamplifier Silicon based transducer systems Hand-held analytic instruments pH probe buffer amplifier Fire and smoke detection systems Charge amplifier for piezoelectric transducers

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
