TI LM62CIM3-NS

The LM62 is a precision IC temperature sensor that operates from a single +3.0V supply and measures temperatures over a 0°C to +90°C range. The LM62 output voltage is linearly proportional to Celsius temperature at +15.6 mV/°C with a DC offset of +480mV, which allows temperatures as low as 0°C to be read without a negative supply. The LM62 nominal output voltage range is +480mV to +1884mV for a temperature range of 0°C to +90°C. The LM62 is factory-trimmed to ±2.0°C accuracy at room temperature and +2.5°C/−2.0°C over the full 0°C to +90°C range. The LM62's linear output, +480mV offset, and factory calibration simplify the external circuitry required to read temperatures as low as 0°C in single-supply environments. Because the LM62 quiescent current is less than 130μA, self-heating in still air is limited to a very low 0.2°C. The LM62 is inherently shutdown-capable, as its low power consumption allows it to be powered directly from the output of many logic gates.
