    ... 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. ...

    ... It is quite common to use large values of feedback resis- tance with amplifiers with ultra-low input curent, like the LMC6042. Although the LMC6042 is highly stable over a wide range of operating conditions, certain precautions must be met to achieve the desired pulse response when a large feedback resistor is used. Large feedback resistors and even small values of input capacitance, due to transducers, photo- diodes, and circuit board parasitics, reduce phase margins ...

    ... The extremely high input impedance, and low power con- sumption, of the LMC6042 make it ideal for applications that require battery-powered instrumentation amplifiers. Ex- amples of these types of applications are hand-held pH probes, analytic medical instruments, magnetic field detec- tors, gas detectors, and silicon based pressure transducers. ...
