Digital Temperature Sensors and Thermal
Watchdog with Bus Lockup Protection
(T
The MAX7500–MAX7504 temperature sensors measure
temperature, convert the data into digital form using a
sigma-delta ADC, and communicate the conversion
results through an I
face. These devices accept standard I

MAX7500 features three address select lines (A0, A1,
A2) while the MAX7501–MAX7504 feature two address
select lines (A0, A1) and a RESET input. The
MAX7500–MAX7504 operate from +3.0V to +5.5V sup-
ply voltages and consume 250µA of supply current.
