6.5 Electrical Characteristics

The following specifications apply for VA = VD = VC = 3.3 V, CL = 10 pF, and fINCLK = 15 MHz unless otherwise specified. All

other limits TA = 25°C.

(1)

Test limits are ensured to TI's AOQL (Average Outgoing Quality Level).

(2)

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.

(3)

The analog inputs are protected as shown in Figure 1. Input voltage magnitudes beyond the supply rails will not damage the device,

provided the current is limited per Note 4 under the Absolute Maximum Ratings table. However, input errors will be generated If the

input goes above VA and below AGND.
