(1)

To ensure accuracy, it is required that VA and VREFIN be well bypassed.

(2)

Typical figures are at TJ = 25°C, and represent most likely parametric norms. Test limits are specified to AOQL (Average Outgoing

Quality Level).

(3)

This parameter is specified by design or characterization and is not tested in production.

7.5 Electrical Characteristics

The following specifications apply for VA = 2.7 V to 5.5 V, VREFIN = VA, CL = 200 pF to GND, fSCLK = 30 MHz, input code range

3 to 252. All limits are at TA = 25°C, unless otherwise specified.
