(3) Definitions of A/D Converter Terms
DS07–12627–6E
• Resolution
• Linearity error (unit: LSB)
• Differential linear error (unit: LSB)
• Total error (unit: LSB)
It indicates the level of analog variation that can be distinguished by the A/D converter.
When the number of bits is 10, analog voltage can be divided into 2
It indicates how much an actual conversion value deviates from the straight line connecting
the zero transition point (“00 0000 0000” ← → “00 0000 0001”) of a device to
the full-scale transition point (“11 1111 1111” ← → “11 1111 1110”) of the same device.
It indicates how much the input voltage required to change the output code by 1 LSB deviates from an
ideal value.
It indicates the difference between an actual value and a theoretical value. The error can be caused by a
zero transition error, a full-scale transition errors, a linearity error, a quantum error, or noise.
