SM73710
October 5, 2011
2.7V, SOT-23 Temperature Sensor
General Description
The SM73710 is a precision integrated-circuit temperature
sensor that can sense a −40°C to +125°C temperature range
while operating from a single +2.7V supply. The SM73710's
output voltage is linearly proportional to Celsius (Centigrade)
temperature (+6.25 mV/°C) and has a DC offset of +424 mV.
The offset allows reading negative temperatures without the
need for a negative supply. The nominal output voltage of the
SM73710 ranges from +174 mV to +1205 mV for a −40°C to
+125°C temperature range. The SM73710 is calibrated to
provide accuracies of ±2.0°C at room temperature and ±4°C
over the full −40°C to +125°C temperature range.
The SM73710's linear output, +424 mV offset, and factory
calibration simplify external circuitry required in a single sup-
ply environment where reading negative temperatures is re-
quired. Because the SM73710's quiescent current is less than
110 μA, self-heating is limited to a very low 0.1°C in still air in
the SOT-23 package. Shutdown capability for the SM73710
is intrinsic because its inherent low power consumption allows
it to be powered directly from the output of many logic gates.
