(1)

LSB = Least Significant BIt

(2)

The difference in the first code transition 000...000 to 000...001 from the ideal value of GND + 1 LSB.

(3)

The difference in the last code transition 011...111 to 111...111 from the ideal value of VDD - 1 LSB with the offset error removed.

(4)

The absolute difference from the ideal transfer function of the converter. This specification is similar to INL error except the effects of

offset error and gain error are included.

(5)

The 2nd through 10th harmonics are used to determine THD.

(6)

Input frequency where the amplitude of the digitized signal has decreased by 0.1 dB or 3 dB.

(7)

Ideal input span which does not include gain or offset errors.
