Description

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.
