LM50 SOT-23 Single-Supply Centigrade Temperature Sensor
General Description
The LM50 is a precision integrated-circuit temperature sensor that can sense a −40˚C to +125˚C temperature range using a single positive supply.
The LM50’s output
voltage is linearly proportional to Celsius (Centigrade) temperature (+10 mV/˚C) and has a DC offset of +500 mV.
The offset allows reading negative temperatures without the need for a negative supply.
The ideal output
voltage of the LM50 ranges from +100 mV to +1.
75V for a −40˚C to +125˚C temperature range.
The LM50 does not require any external calibration or trimming to provide accuracies...
