I2C TIMING SPECIFICATIONS
Guaranteed by initial characterization. All values measured with input filtering enabled. CB refers to capacitive load on the bus line.
tr and tf measured between 0.3 VDD and 0.7 VDD.
High speed mode timing specifications apply to the AD7993-1/AD7994-1 only. Standard and fast mode timing specifications apply to
both the AD7993-0/AD7994-0 and the AD7993-1/AD7994-1. See Figure 2.
Unless otherwise noted, VDD = 2.7 V to 5.5 V; REFIN = 2.5 V; TA =TMIN to TMAX.
