NOTES
1
Guaranteed by characterization. All input signals are specified with tr = tf = 5 ns (10% to 90% of V
) and timed from a voltage level of 1.6 V.
2
A Version timing specifications apply to the AD7477 S Version and AD7478 S Version; B Version timing specifications apply to the AD7476 S Version.
3
3 V specifications apply from V
DD
= 2.7 V to 3.6 V for A Version; 3 V specifications apply from V
DD
= 2.35 V to 3.6 V for B Version; 5 V specifications apply from
V
= 4.75 V to 5.25 V.
4
Mark/Space ratio for the SCLK input is 40/60 to 60/40.
5
Measured with the load circuit of Figure 1 and defined as the time required for the output to cross 0.8 V or 2.0 V.
6
t
is derived from the measured time taken by the data outputs to change 0.5 V when loaded with the circuit of Figure 1. The measured number is then extrapolated
to remove the effects of charging or discharging the 50 pF capacitor. This means that the time, t
8
, quoted in the Timing Specifications is the true bus relinquish time
of the part and is independent of the bus loading.
