MSM65355

Recognizable minimum input analog value.

This can be resolved into 28=256, that is, VRH ∏ 256 in

8 bits.

Deviation between ideal conversion characteristics as an 8-bit

A/D converter and actual conversion characteristics. (Quantization

error not included.)

Ideal conversion characteristics means a step, where voltage is

divided between VRH and AGND into 256.

Shows the smoothness of conversion characteristics.

1LSB= VRH ∏ 256 is ideal for analog input voltage width

corresponding to change per 1 bit of digital output.

The differential linearity error is the deviation between this ideal bit

size and a 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.
