See Figure 23 for an example of configuring a conver-
sion scan for internal temperature, PGAOUT1, and
ADCIN1 in clock mode 11 using the internal reference.
Timing symbols are referenced in the Miscellaneous
Timing Characteristics section.
See Figure 24 for an example of configuring a conver-
sion scan for ADCIN1, external temperature sensor 2,
and PGAOUT2 in clock mode 11 using the internal ref-
erence. Timing symbols are referenced in the
Miscellaneous Timing Characteristics section.
Table 26 shows some examples of temperature settings
in two’s-complement form.

Each DAC stage is configurable for leapfrog operation
by using the 8-bit coarse DACs in conjunction with the
10-bit fine DAC. Use the following procedure for setting
18 bits of resolution:
1) Write to the Coarse DAC1/DAC2 Write-Through Low
2) Write to the Coarse DAC1/DAC2 Write-Through High
with I
Wiper Input register (THRULO1/THRULO2)
Wiper Input register (THRUHIGH1/THRUHIGH2) with
a value one higher or one lower than written to the
low wiper register.
