(1) Resolution: Minimum input analog value recognized. For 10-bit resolution, this is (V
(2) Linearity error: Difference between the theoretical and actual conversion characteristics.
(3) Differential linearity error: Difference between the theoretical and actual input voltage
(4) Zero scale error: Difference between the theoretical and actual conversion characteristics at
(5) Full scale error: Difference between the theoretical and actual conversion characteristics at
Aground) ÷ 1024.
(Note that it does not include quantization error.) The theoretical conversion characteristic
divides the voltage range between V
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
Aground) ÷ 1024.
the point where the digital output switches from “0x000” to “0x001.”
the point where the digital output switches from “0x3FE” to “0x3FF.”
