AD7470/AD7472
–14–
Mode 1
Figure 14 shows the AD7472 conversion sequence in Mode 1
using a throughput rate of 500 kSPS and a clock frequency of
26 MHz. At 5 V supply, the current consumption for the part
when converting is typically 2 mA, and the quiescent current is
typically 650
A. The conversion time of 531.66 ns contributes
2.658 mW to the overall power dissipation in the following way:
(531.66 ns/2
s) × (5 × 2 mA) = 2.658 mW
The contribution to the total power dissipated by the remaining
1.468
s of the cycle is 2.38 mW.
(1.468
s/2 s) × (5 × 650 A) = 2.38 mW
Thus the power dissipated during each cycle is
2.658 mW + 2.38 mW = 5.038 mW

Figure 15 shows the AD7472 conversion sequence in Mode 2
using a throughput rate of 500 kSPS and a clock frequency of
26 MHz. At 5 V supply, the current consumption for the part
when converting is typically 2 mA, while the sleep current is 1

max. The power dissipated during this power-down is negli-
gible, and is thus not worth considering in the total power fig-
ure. During the wake-up phase, the AD7472 will draw 650
