Force-Sense Switches ______________Force-Sense Philosophy When a precise voltage must be applied to a load that draws appreciable current, the resistance of the con- ductors connecting the source and the load can degrade the load voltage. The resistance of the con- ...

Philosophy When measuring a precise voltage from a high-resis- tance source, or when measuring a very small current or forcing it into a load, unwanted leakage currents can degrade the results. These leakage currents may exist in the insulation ...

... An enable pin, EN, turns all switches off when driven to logic high. The MAX4554 is also fully specified for oper- ation with +20V and -10V supplies. The MAX4555 con- tains four independent SPDT, NC switches; two are force switches and two are sense switches. The MAX4556 contains three independent SPDT switches ...

... The MAX4554/MAX4555/MAX4556 operate with bipolar supplies between ±4.5V and ±18V. However, since all factory characterization is done with ±15V supplies (and +20V, -10V for MAX4554), operation at other sup- plies is not guaranteed. The V+ and V- supplies need not be symmetrical, but their sum cannot exceed the absolute maximum rating of 44V (see Absolute Max- imum Ratings ) ...
