PRODUCTION DATA
The LM60 device is a precision analog bipolar temperature sensor that can sense a −40°C to +125°C temperature range while operating from a single 2.7V supply. The output voltage of the LM60 is linearly proportional to Celsius (Centigrade) temperature (6.25mV/°C) and has a DC offset of 424mV. The offset allows reading negative temperatures with a single positive 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 ±2.0°C at room temperature and ±3°C over the full −25°C to +125°C (for Legacy chip) or −40°C to +125°C (for New chip)temperature range.
With a 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.
The output of the LM60 is a Class A base emitter follower, thus the LM60 can source quite a bit of current while sinking less than 1µA. In any event load current must be minimized to limit the contribution to the total temperature error.
