CMOS Dual Micropower Operational Amplifier 		Click link to Download

Features
  • Low supply current: 10 µA/Amp (typ)
  • Operates from 4.5V to 15V 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 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.

    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.
