16 Bits No Missing Codes (Full-Supply Range,

The ADS8317 is a 16-bit, sampling, analog-to-digital

High or Low Grade)

(A/D) converter specified for a supply voltage range

from 2.7V to 5.5V. It requires very little power, even

±0.8LSB typ, ±1.5LSB max INL

spend most of its time in the power-down mode. For

+0.7LSB typ, +1.25LSB max DNL

example, the average power dissipation is less than
