1.
VDD_IO and AVDD should be supplied separately.
2.
Resolution: Minimum input analog value recognized. For 10-bit resolution, this is (VREF – AGND) ÷ 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 VREF and AGND
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 (VREF – AGND) ÷ 1024.
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.”
