- Detailed Description
Figure 28. Unipolar Transfer Function
8.6 Reducing Supply Current
Power consumption can be reduced significantly by powering down the devices between conversions.
Figure30
shows a plot of an average
supply current versus sampling rate.
Wake-up time (t
WAKE
) can also factor into reduced power consumption. t
WAKE
is defined as the time fromwhen pin SHDNN is deasserted to
the time when a conversion may be initiated
(see Figure 29)
.
Figure 29. Shutdown Sequence Timng Diagram
For the AS1526 using the internal reference, t
WAKE
depends on the time in shutdown mode
(see Figure 31)
since the external 4.7μF reference
bypass capacitor slowly loses charge during shutdown. The wakeup time for AS1526 and AS1527 using an internal reference are largely
dependent on the external reference’s power-up time. The wakeup time for the ADC itself fromshutdown mode is approximately 4μs.
