RT N is tied to REFOUT then the analog input range becomes
0 V to 2 V. T he fixed 2 V analog input voltage span of the ADC
can range from 1 V to 3 V (RT N = 0 V) to 0 V to 2 V (RT N =
2 V), i.e., with proper biasing, an input signal range from 0.3 V
to 2.3 V can be covered. Both the relative accuracy and differen-
tial nonlinearity performance remains essentially unchanged in
this mode while the SNR and T HD performance are typically
2 dB to 3 dB worse than standard.
Changing the Analog Input Voltage Range
By biasing the RT N pin above AGND it is possible to change
the analog input voltage range from its V
