Force-Sense Switches
General Description
The MAX4554/MAX4555/MAX4556 are
CMOS analog ICs configured as force-sense switches for Kelvin sensing in automated test equipment (ATE).
Each part contains high-current, low-resistance switches for forcing current, and higher resistance switches for sensing a
voltage or switching guard signals.
The MAX4554 contains two force switches, two sense switches, and two guard switches configured as two triple-pole/single-throw (3PST) normally open (NO) switches.
The MAX4555 contains four independent single-pole/single-throw (SPST) normally closed (NC) switches, two force switches, and two sense switches.
The MAX4556 contains three indepe...
