25.2.1
The full range of voltage reference cannot be realized
due to the construction of the module. The transistors
on the top and bottom of the resistor ladder network
(Figure 25-1) keep
approaching the reference source rails. The voltage
reference is derived from the reference source; there-
fore, the voltage reference output changes with
fluctuations in that source. Refer to the product data
sheet for the electrical specifications. Table 25-3
contains the typical output impedances for the CV
module.
TABLE 25-3:
25.2.2
This initialization sequence, shown in Example 25-1,
configures the CV
put enabled, high range, and set output for maximum
(2.37V).
