Programmable 360° Inclinometer
ADIS16203
FEATURES angle data in a convenient format that can be accessed using a
serial peripheral interface (SPI). The SPI interface provides access
to multiple measurements: 360° linear inclination angles, ±180°
linear incline angles, temperature, power supply, and one auxiliary
analog input. Easy access to calibrated digital sensor data provides
developers with a system-ready device, reducing development
time, cost, and program risk. 0° to 360° Inclinometer

No fix MANUAL FLASH/EE MEMORY UPDATE FAILURES [er001]
Background Issue
Workaround Related Issues The ADIS16203 uses a dual memory structure to maintain its operational configuration. The RAM register structure
controls the operation of the device, and the Flash/EE memory contents determine what is loaded into the RAM at
startup and during reset recovery events. The Flash/EE memory is updated by using a control bit in the COMMAND register
of this part.
Flash/EE memory update fails at a rate of approximately 5%.
Date Code 0722 and older can exhibit this behavior. …
