Internal Reference
To use the MAX1110/MAX1111 with the internal refer-
ence, connect REFIN to REFOUT. The full-scale range
of the MAX1110/MAX1111 with the internal reference is
typically 2.048V with unipolar inputs, and ±1.024V with
bipolar inputs. The internal reference should be
bypassed to AGND with a 1F capacitor placed as
close to the REFIN pin as possible.
Transfer Function
Table 4 shows the full-scale voltage ranges for unipolar
and bipolar modes. Figure 15 depicts the nominal, unipo-
lar I/O transfer function, and Figure 16 shows the bipolar
I/O transfer function when using a 2.048V reference.
Code transitions occur at integer LSB values. Output cod-
ing is binary, with 1LSB = 8mV (2.048V/256) for unipolar
operation and 1LSB = 8mV [(2.048V/2 - -2.048V/2)/256]
for bipolar operation.
