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 supply environment where reading
negative temperatures is required. 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.
