NOTES
1See AD6600 Timing Diagrams.
2All switching specifications tested by driving ENC and
ENC differentially.
3This specification IS NOT a function of Encode period and duty cycle.
4This specification IS a function of Encode period and duty cycle.
5CLK2
× referenced to 2.0 V crossing; digital output levels referenced to 0.8 V and 2.0 V crossings; all outputs with 10 pF load.
6For these particular specifications, the 25
°C specification is valid from 25°C to 85°C. The Full temperature specification includes cold temperature extreme and
covers the entire range, –40
°C to +85°C.
Specifications subject to change without notice.
