Internal Reference
The MAX1298 has a 2.50V internal reference, while the
MAX1299 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 100礎 capability. Bypass REF to GND with a 0.1礔
(min) capacitance. Wake-up time is C x 2.5 x 10
4
s for
the MAX1298 and C x 1.2 x 10
4
s for the MAX1299.
External Reference
The MAX1298 can directly accept reference voltages at
REF from 0.8V to 2.5V, while the MAX1299 can directly
accept reference voltages from 0.8V to 1.2V. Bypass
REF to GND with a 0.1礔 capacitor. Temperature mea-
surements always use internal reference.
Power Modes
The MAX1298 (MAX1299) typically requires supply cur-
rents of 380礎 (350礎) or 310礎 (280礎) when per-
forming voltage conversions at 100% duty cycle with
internal or external references, respectively. The differ-
ence reflects the power requirement of an internal refer-
ence buffer amplifier that can accommodate external
loads. Temperature conversions at 100% duty cycle
increase supply currents to 440礎 (400礎) through
additional amplification, buffer, and bias circuitry that is
otherwise inactive.
