NOTES
1Sample tested at –25
°C to ensure compliance. All input signals are specified with tr = tf = 5 ns (10% to 90% of 5 V) and timed from a voltage level of 1.6 V.
2See Figures 8 to 11.
3The AD7890 is production tested with f
CLK IN at 2.5 MHz. It is guaranteed by characterization to operate at 100 kHz.
4Specified using 10% and 90% points on waveform of interest.
5These numbers are measured with the load circuit of Figure I and defined as the time required for the output to cross 0.8 V or 2.4 V.
6These numbers are derived from the measured time taken by the data output to change 0.5 V when loaded with the circuit of Figure 1. The measured number is then
extrapolated back to remove effects of charging or discharging the 50 pF capacitor. This means that the times quoted in the timing characteristics are the true bus re-
linquish times of the part and as such are independent of external bus loading capacitances.
