    The L9966 is an automotive grade IC designed to be used as sensors interface. Up to 15 channels are available for analog sensing, resistance measurement and digital sensing (e.g. temperature, lambda, pressure, position sensors).


    The L9966 allows replacing a number of discrete components and it gives the possibility to change the sensors across different applications without modifying the PCB hardware.


    Target applications are Engine Control Units and Body/Chassis Modules.
