SNAS487A – SEPTEMBER 2009 – REVISED APRIL 2013

Electrical Characteristics (continued)

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

Boldface limits apply for TA = TMIN to TMAX; all other limits TA = 25°C.

(1)

The analog inputs are protected as shown in Figure 4. 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.

(2)

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

(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.
