(1)

The inputs are protected as shown below. Input voltage magnitudes above VA or below GND will not damage this device, provided

current is limited per Note 3 under the Absolute Maximum Ratings. However, errors in the A/D conversion can occur if the input goes

above VA or below GND by more than 100 mV. As an example, if VA is +3.3V, the full-scale input voltage must be ≤+3.4V to ensure

accurate conversions.

(2)

To ensure accuracy, it is required that |VA–VD| ≤ 100 mV and separate bypass capacitors are used at each power supply pin.

(3)

With the test condition for VREF = +1.0V (2VP-P differential input), the 10-bit LSB is 1.95 mV.

(4)

Typical figures are at TA = 25°C, and represent most likely parametric norms at the time of characterization. The typical specifications

are not ensured.
