Internal Referenc e
To use the MAX1112/MAX1113 with the internal refer-
ence, connect REFIN to REFOUT. The full-scale range
of the MAX1112/MAX1113 with the internal reference is
typically 4.096V with unipolar inputs, and ±2.048V with
bipolar inputs. The internal reference should be
bypassed to AGND with a 1μF capacitor placed as
close to the REFIN pin as possible.
T ransfer Func tion
Table 4 shows the full-scale voltage ranges for unipolar
and bipolar modes. Figure 15 depicts the nominal,
unipolar I/O transfer function, and Figure 16 shows the
bipolar I/O transfer function when using a 4.096V refer-
ence. Code transitions occur at integer LSB values.
Output coding is binary, with 1LSB = 16mV
(4.096V/256) for unipolar operation and 1LSB = 16mV
[(4.096V/2 - -4.096V/2)/256] for bipolar operation.
