(1)

The analog inputs are protected as shown below. Input voltage magnitudes up to VA + 300 mV or to 300 mV below GND will not

damage this device. However, errors in the A/D conversion can occur if the input goes above VA or below GND by more than 100 mV.

For example, if VA is 3.3VDC the input voltage must be ≤3.4VDC to ensure accurate conversions.

(2)

To ensure accuracy, it is required that VA, VD, VP and VDR be well bypassed. Each supply pin should be decoupled with separate

bypass capacitors.

(3)

Typical figures are at TJ = 25°C, and represent most likely parametric norms. Test limits are specified to Texas Instrument's AOQL

(Average Outgoing Quality Level).
