CONFIGURATION
AIN
Internal reference turns off after scan is complete. If
internal reference is turned off, there is a programmed
delay of 218 external-conversion clock cycles.
00
Internal (DAC
and ADC)
Temperature
Internal reference required. There is a programmed
delay of 244 external-conversion clock cycles for the
internal reference. Temperature-sensor output appears
at DOUT after 188 further external clock cycles.
AIN6
AIN
Internal reference not used.
01
External single-
ended (REF1
for DAC and
REF2 for ADC)
Temperature
Internal reference required. There is a programmed
delay of 244 external-conversion clock cycles for the
internal reference. Temperature-sensor output appears
at DOUT after 188 further external clock cycles.
REF2
AIN
Default reference mode. Internal reference turns off
after scan is complete. If internal reference is turned
off, there is a programmed delay of 218 external-
conversion clock cycles.
