 We noticed in the nRF5 SAADC libraries the presence of a low_power bit setting on the nrf_drv_saadc_config_t config. 
 
 
 But, we were not able to find such low_power_mode mother in Zephyr, neither in the nrfx_saadc libs. 
 Said that:

&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;nrf_drv_saadc.h is an older nRF5 SDK driver, pre-nrfx drivers, and will not be applicable for zephyr.&lt;/p&gt;
[quote user=""]1) How should we enable the &lt;span&gt;low_power_mode&amp;nbsp;&lt;/span&gt;mode on the SAADC in Zephyr?[/quote]
&lt;p&gt;The important part for low power SAADC is to stop/disable after a conversion is done. This is automatically handled if you use zephyr&amp;#39;s &amp;quot;adc&amp;quot; driver (which uses nrfx_saadc underneath)&lt;/p&gt;
[quote user=""]2) Would that &lt;span&gt;low_power_mode&amp;nbsp;&lt;/span&gt;mode be supported on the nRF9160 SAADC?[/quote]
&lt;p&gt;Yes, the &amp;quot;adc&amp;quot; library shall be low power.&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Kind regards,&lt;/p&gt;
