ADC calculator – voltage to RAW value

Converts an analog voltage into the raw converter value and back. Resolution is configurable from 1 to 16 bits and the reference voltage is free to choose, which makes the calculator useful when sizing the measuring range of a microcontroller analog input, for example in the PIC and STM32 families.

Sizing the measuring range is only the first step — the schematic, the board and the firmware follow. If you need a finished device rather than just the numbers, see our custom electronics design offer.
