Dynamic Converter Electrical Characteristics (continued)

Unless otherwise specified, the following specifications apply: AGND = DRGND = 0V, VA = VDR = +3.0V, Internal VREF =

+1.2V, fCLK = 80 MHz, VCM = VCMO, CL = 5 pF/pin, . Typical values are for TA = 25°C. Boldface limits apply for TMIN ≤ TA ≤

TMAX. All other limits apply for TA = 25°C

(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 Absolute Maximum Ratings, Note 4. However, errors in the A/D conversion can occur if the input goes above 2.6V

or below GND as described in the Operating Ratings section.

(2)

With a full scale differential input of 2VP-P , the 14-bit LSB is 122.1 µV.

(3)

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

specifications are not ensured.
