16.9.5
The ZoominADC™ 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:
Finally, remember that power reduction is typically traded off with reduced linearity, larger noise and slower
maximum sampling speed.

Operate the acquisition chain with a reduced supply voltage V
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 IB_AMP_PGA[1:0] and
IB_AMP_ADC[1:0]. (This reduces the maximum sampling frequency according to Table 16-26.)
Reduce internal RC oscillator frequency and/or sampling frequency.
