| Mar 22 at 14:17 | comment | added | Blueman | Okay, I see. I can set it to power-down mode. and made the communication for it already. So I'm happy that it should work with it. Im not sure about the circuitry for the MCP6V19. I'll try and figure out what i need for it. I might ask about it and accept the answer when it's working. Thanks again. | |

A low sample rate application could very well draw fractional µA with a well-optimized solution; battery monitors are such an application, for example. The ADC claims ~20µA static mode, ~0.3 in shutdown, so if you need the reduction, but have no means to switch it to power-down mode, that might require a design change. (Probably those come from GPIOs and this is a simple change in programming.) You may also not need further reduction, which is fine. | |
