NOTES
1
See Figure 1. Hs-Mode timing specification apply to the AD7992-1 only, Standard, Fast Mode Timing specifications apply to both the
AD7992-0 and AD7992-1. C
B
refers tothe capacitance load on the bus line.
2
The SDA and SCL timing is measured with the input filters enabled. Switching off the input filters improves the transfer rate but has a nega-
tive effect on EMC behavior of the part.
4
Input filtering on both the SCL and SDA inputs suppress noise spikes that are less than 50ns or 10ns for Fast Mode or High-Speed mode
respectivley.
Specifications subject to change without notice.
