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.

See Figures 8 to 11.
3
T he AD7890 is production tested with f
at 2.5 MHz. It is guaranteed by characterization to operate at 100 kHz.
4
Specified using 10% and 90% points on waveform of interest.
5
T hese 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.
6
T hese 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. T he measured number is then
extrapolated back to remove effects of charging or discharging the 50 pF capacitor. T his 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.
