SX8724
ZoomingADC for Pressure and Temperature Sensing
Power Reduction
The ZoomingADC is particularly well suited for low-power applications. When very low power consumption is
of primary concern, such as in battery operated systems, several parameters can be used to reduce power
consumption as follows:
1.
Operate the acquisition chain with a reduced supply voltage VDD.
2.
Disable the PGAs which are not used during analog-to-digital conversion with ENABLE[3:0].
3.
Disable all PGAs and the ADC when the system is idle and no conversion is performed.
4.
Use lower bias currents in the PGAs and the ADC using the control words IB_AMP_PGA[1:0] and
IB_AMP_ADC[1:0].
5.
Reduce sampling frequency.
Finally, remember that power reduction is typically traded off with reduced linearity, larger noise and slower
maximum sampling speed.
Recommended Design for Other 2-WIRE Devices Connection
SX8724 does not support multiple devices on the same 2-WIRE bus. A separate 2-WIRE bus should be used to
address other devices as seen on the following schematic.
