LM62BIM3

The LM62BIM3 is a precision Temperature Sensor that can sense a 0 to +90°C temperature range while operating from a single +3.0V supply. The device's output voltage is linearly proportional to Celsius (Centigrade) temperature (+15.6mV/°C) and has a DC offset of +480mV. The offset allows reading temperatures down to 0°C without the need for a negative supply. The nominal output voltage of the device ranges from +480mV to +1884mV for a 0 to +90°C temperature range. The device is calibrated to provide accuracies of ±2.0°C at room temperature and +2.5°C/-2.0°C over the full 0 to +90°C temperature range. The LM62's linear output, +480mV offset and factory calibration simplify external circuitry required in a single supply environment where reading temperatures down to 0°C is required. Because the LM62's quiescent current is less than 130µA, self-heating is limited to a very low 0.2°C in still air.
