AD7940
POWER VS. THROUGHPUT RATE
By using the power-down mode on the AD7940 when not
converting, the average power consumption of the ADC
decreases at lower throughput rates. Figure 19 shows how as the
throughput rate is reduced, the part remains in its shutdown
state longer, and the average power consumption over time
drops accordingly.
Rev. 0 | Page 15 of 20
For example, if the AD7940 is operated in a continuous sam-
pling mode, with a throughput rate of 10 kSPS and an SCLK of
2.5 MHz (V
DD
= 3.6 V), and the device is placed in power-down
mode between conversions, the power consumption is calcu-
lated as follows. The maximum power dissipation during nor-
mal operation is 6.84 mW (V
DD
= 3.6 V). If the power-up time
from power-down is 1 μs, and the remaining conversion time is
6.4 μs, (using a 16 SCLK transfer), then the AD7940 can be said
to dissipate 6.84 mW for 7.4 μs during each conversion cycle.
With a throughput rate of 10 kSPS, the cycle time is 100 μs. For
the remainder of the conversion cycle, 92.6 μs, the part remains
in power-down mode. The AD7940 can be said to dissipate
1.08 μW for the remaining 92.6 μs of the conversion cycle.
Therefore, with a throughput rate of 10 kSPS, the average power
dissipated during each cycle is
(7.4/100) × (6.84 mW) + (92.6/100) × (1.08 μW) = 0.51 mW
Figure 19 shows the power dissipation versus the throughput
rate when using the power-down mode with 3.6 V supplies and
a 2.5 MHz SCLK.
