AS1526/AS1527
Data Sheet
- Detailed Description
Transfer Function
The data output from the AS1526/AS1527 is binary (unipolar), and
Figure 28
depicts the nominal transfer function.
Code transitions occur midway between successive integer LSB values.
Note:
If V
REF
= +2.50V, then 1 LSB = 2.44mV (2.50V/1024).
Figure 28. Unipolar Transfer Function
Reducing Supply Current
Power consumption can be reduced significantly by powering down the devices between conversions.
Figure 30
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 from when pin
SHDNN is deasserted to the time when a conversion may be initiated
(see Figure 29)
.
Figure 29. Shutdown Sequence Timing 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 from shutdown mode is approximately 4μs.
