Reference Selection
Select between internal and external voltage modes
through bit REF of the configuration byte. Set REF = 1
for internal reference mode and REF = 0 for external
reference mode.
Internal Reference
The MAX1098 has a 2.50V internal reference, while the
MAX1099 has a 1.20V internal reference. Both are fac-
tory trimmed for accuracy. When internal reference is
selected, REF can be used to drive an external load
with 100μA capability. Bypass REF to GND with a 0.1μF
minimum capacitance. Wake-up time is C x 2.5 x 10
4
s
for the MAX1098 and C x 1.2 x 10
4
s for the MAX1099.
External Reference
The MAX1098 can directly accept reference voltages at
REF from 0.8V to 2.5V, while the MAX1099 can directly
accept reference voltages from 0.8V to 1.2V. Bypass
REF to GND with a 0.1μF capacitor. Temperature mea-
surements always use internal reference.
Power Modes
The MAX1098/(MAX1099) typically requires supply cur-
rents of 380μA (350μA) or 310μA (280μA) when per-
forming voltage conversions at 100% duty cycle with
internal or external references, respectively. The differ-

These 2 bits select the desired power mode (Table 3).
A logic high enables the internal reference. A logic low disables the internal reference and
selects the external reference mode.
