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.
Angular accuracy is not guaranteed <50 Hz reference frequency.
Linearity derates from 500 kHz–1000 kHz @ 0.0017%/kHz.
Refer to Definition of Linearity, “The AD2S83 as a Silicon Tachogenerator.”
Worst case reversion error at temperature extremes.
Velocity output offset dependent on value for R6.
Refer to timing diagram.
Busy pulse guaranteed up to a VCO rate of 900 kHz.
