NOTES
1Angular accuracy is not guaranteed <50 Hz reference frequency.
2Linearity derates from 500 kHz–1000 kHz @ 0.0017%/kHz.
3Refer to Definition of Linearity, “The AD2S83 as a Silicon Tachogenerator.”
4Worst case reversion error at temperature extremes.
5Velocity output offset dependent on value for R6.
6Refer to timing diagram.
7Busy pulse guaranteed up to a VCO rate of 900 kHz.
All min and max specifications are guaranteed. Specifications in boldface are tested on all production units at final electrical test.
Specifications subject to change without notice.
