8 Application hints
8.1 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:
Operate the acquisition chain with a reduced supply voltage VBATT.
Disable the PGAs which are not used during analog-to-digital conversion with Enable[3:0].
Disable all PGAs and the ADC when the system is idle and no conversion is performed.
Use lower bias currents in the PGAs and the ADC using the control words IbAmpPga[1:0] and IbAmpAdc[1:0].
Reduce sampling frequency.
Finally, remember that power reduction is typically traded off with reduced linearity, larger noise and slower maximum
sampling speed.
