LMC6042 www.ti.com SNOS611E – AUGUST 1999 – REVISED MARCH 2013 LMC6042 CMOS Dual Micropower Operational Amplifier Check for Samples: LMC6042 FEATURES 1 2 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 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 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 batterypowered 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 TI's advanced Double-Poly Silicon-Gate CMOS process. See the LMC6041 for a single, and the LMC6044 for a quad amplifier with these feature...
