ADMT4000 Overview
The ADMT4000 is a magnetic turn count sensor capable of recording the number of rotations of a magnetic system even while the device is powered down. On Data Sheet ADMT4000 True Power-On Multiturn Sensor power-up, the device can be interrogated to report the absolute position of the system. The absolute position is reported through a serial-peripheral interface (SPI).
