2. Resolution: Minimum input analog value recognized. For 10-bit resolution, this is (V – A ) ÷ 1024.

3. Linearity error: Difference between the theoretical and actual conversion characteristics. (Note that it does not include quantization error.) The theoretical conversion characteristic divides the voltage range between V and A
REF
GND
into 1024 equal steps.
4. Differential linearity error: Difference between the theoretical and actual input voltage change producing a 1-bit change in the digital output anywhere within the conversion range. This is an indicator of conversion characteristic
smoothness. The theoretical value is (V – A ) ÷ 1024.
REF
GND
5. Zero scale error: Difference between the theoretical and actual conversion characteristics at the point where the digital output switches from “0x000” to “0x001.”
6. Full scale error: Difference between the theoretical and actual conversion characteristics at the point where the digital output switches from “0x3FE” to “0x3FF.”
