The minimum input analog value which can be recognized. It can
decompose into 2
The deviation between the ideal conversion characteristic as a 8-bit
A/D converter and the actual conversion characteristic is said.
(Therefore, a quantization error is not included.) The ideal
conversion characteristic means the step which divided the voltage
between V
Digital output "000H" to "001H" changes, and the deviation of the
ideal conversion characteristic of a point and the actual conversion
characteristic is
Digital output "0FEH" to "0FFH" changes, and the deviation of the
ideal conversion characteristic of a point and the actual conversion
characteristic is said.
The smoothness of the conversion characteristic is shown, and
ideally, the width of the analog input voltage corresponding to
change for 1 bit of digital outputs is 1LSB= (V
the deviation of this ideal bit size and the bit size in the arbitrary
points of the conversion range.
