1 Maximum bus capacitance is limited to 400 pF.
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 negative effect on EMC behavior
of the part.
3 Input filtering on the SCL and SDA inputs suppresses noise spikes that are less than 50 ns for fast mode.
4 Refer to tRDAC_R-PERF and tRDAC_NORMAL for RDAC register write operations.
5 Refer to t
MEMORY_READ
and tMEMORY_PROGRAM for memory commands operations.
6 Maximum time after VDD VSS is equal to 2.5 V.
