Here is Tolic from Edinburgh.
Going to control moving system acceleration and inclination with reference to gravity. Expected inclination range is about ±5˚ expected accuracy 0.1˚ System will be controlled by PIC18F MCU. What AD parts can be recommended?
Since you mention that the system will be moving, what level of acceleration are you anticipating, in addition to the gravity contribution? Is 0.1 degrees a maximum allowable error? I would exercise care in this definition, as that could greatly influence what must be done to support that objective.
Thanks for fast response.
Expected acceleration will not exceed 2.5g
±0.1º error is a willable value, but life is life...
Let me ask question in another way:
I have to control moving system acceleration and system inclination with reference to gravity. Inclination range is about ±5˚.
Expected level of acceleration, in addition to the gravity contribution will be about 1.8g but not exceed 2.5g.
What AD parts can be recommended and what accuracy can be expected?
Application will be manufactured in small butch production. Each sample will be calibrated and adjusted separately.
We are releasing a brand new product, the ADXL355, at the end of next week, which will be a very good fit for what you are trying to accomplish. I am not able to share a datasheet on this yet, but in approximately one week, it will be available at the following web site: www.analog.com/ADXL355
