SM73710
SM73710 is SOT-23 Temperature Sensor manufactured by National Semiconductor.
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 m V/°C) and has a DC offset of +424 m V. The offset allows reading negative temperatures without the need for a negative supply. The nominal output voltage of the SM73710 ranges from +174 m V to +1205 m V 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 m V 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.
