• Definition of Terms

(1) Resolution: Minimum input analog value recognized. For 10-bit resolution, this is (VREF –

Aground) ÷ 1024.

(2) 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.

(3) 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 – Aground)

÷ 1024.

(4) Zero scale error: Difference between the theoretical and actual conversion characteristics at

the point where the digital output switches from “0x000” to “0x001.”

(5) Full scale error: Difference between the theoretical and actual conversion characteristics at the

point where the digital output switches from “0x3FE” to “0x3FF.”
