1 Sample tested at +25°C to ensure compliance. All input signals are specified with tr = tf = 5 ns (10% to 90% of DVDD) and timed from a voltage level of 1.6 V.
3 fCLKIN duty cycle range is 45% to 55%. fCLKIN must be supplied whenever the AD7707 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 AD7707 is production tested with fCLKIN at 2.4576 MHz (1 MHz for some IDD tests). It is guaranteed by characterization to operate at 400 kHz.
5 These numbers are measured with the load circuit of Figure 2 and defined as the time required for the output to cross the VOL or VOH limits.
6 These numbers are derived from the measured time taken by the data output to change 0.5 V when loaded with the circuit of Figure 2. 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.

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.
