External and Internal References
The MAX1202 can be used with an internal or external
reference, whereas an external reference is required for
the MAX1203. An external reference can be connected
directly at the REF terminal, or at the REFADJ pin.
An internal buffer is designed to provide 4.096V at
REF for both the MAX1202 and the MAX1203. The
MAX1202’s internally trimmed 2.44V reference is
buffered with a gain of 1.68. The MAX1203’s REFADJ
pin is buffered with a gain of 1.64, to scale an external
2.5V reference at REFADJ to 4.096V at REF.
MAX1202 Internal Reference
The MAX1202’s full-scale range using the internal
reference is 4.096V with unipolar inputs and ±2.048V
with bipolar inputs. The internal reference voltage is
adjustable to ±1.5% with the circuit of Figure 17.
