Specifications

Table 5-55 shows the CMPSS DAC static electrical characteristics. Figure 5-41 shows the CMPSS DAC

static offset. Figure 5-42 shows the CMPSS DAC static gain. Figure 5-43 shows the CMPSS DAC static

linearity.

(1)

Includes comparator input referred errors.

(2)

Disturbance error may be present on the CMPSS DAC output for a certain amount of time after a comparator trip.

(3)

Per active CMPSS module.
