NOTES
1
Sample tested at +25
°
C to ensure compliance. All input signals are specified with tr = tf = 5 ns (10% to 90% of DV
DD
) and timed from a voltage level of 1.6 V.
2
See Figures 6 and 7.
3
CLKIN Duty Cycle range is 45% to 55%. CLKIN must be supplied whenever the AD7715 is not in Standby mode. If no clock is present in this case, the
device can draw higher current than specified and possibly become uncalibrated.
4
The AD7715 is production tested with f
CLKIN
at 2.4576MHz (1MHz for some I
DD
tests). It is guaranteed by characterization to operate at 400kHz.
5
These numbers are measured with the load circuit of Figure 1 and defined as the time required for the output to cross the V
OL
or V
OH
limits.
6
These numbers are derived from the measured time taken by the data output to change 0.5V 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 relinquish times of the part and as such are independent of external bus loading capacitances.
7
DRDY
returns high after the first read from the device after an output update. The same data can be read again, if required, while
DRDY
is high although care
should be taken that subsequent reads do not occur close to the next output update.
