3 Description

The LM60-Q1 device 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 to 10V supply. The output voltage of the device is linearly proportional to Celsius (Centigrade) temperature (6.25mV/°C) and has a DC offset of 424mV. The offset allows reading negative temperatures without the need for a negative supply. The nominal output voltage of the device ranges from 174mV to 1205mV for a −40°C to +125°C temperature range. The device is calibrated to provide accuracies of ±3°C at room temperature and ±4°C over the full −40°C to +125°C.

The linear output of the device, 424mV offset, and factory calibration simplify external circuitry required in a single supply environment where reading negative temperatures is required. Because the quiescent current of the device is less than 110μA (for Legacy chip) and 70μA (for New chip), self-heating is limited to a very low 0.1°C in still air in the SOT-23 package. Shutdown capability for the device is intrinsic because the inherent low power consumption allows the device to be powered directly from the output of many logic gates.
