Differential Linearity Error

Zero Scale Error

Full Scale Error

Recognizable minimum input analog value.

This can be resolved into 28 = 256, that is AVDD ÷ 256 in 8 bits.

Deviation between ideal conversion characteristics as an 8-bit A/D converter

and actual conversion characteristics. (Not including quantization error.)

Ideal conversion characteristics means a step which divides voltage between

VRH and LRL into 256.

Smoothness of conversion characteristics.

1LSB = AVDD ÷ 256 is ideal for analog input voltage width corresponding to

change per 1 bit of digital output. Deviation between the ideal bit size and bit

size at arbitrary point in conversion range.

Deviation between ideal conversion characteristics of transfer point for digital

outputs "000H" to "001H" and actual conversion characteristics.

Deviation between ideal conversion characteristics of transfer point for digital

outputs "0FEH" to "0FFH" and actual conversion characteristics.
