... 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 ± ...

... Note 9: Quiescent current is defined in the circuit of Figure 1 . Note 10: For best long-term stability, any precision circuit will give best results if the unit is aged at a warm temperature, and/or temperature cycled for at least 46 hours before long-term life test begins. This is especially true when a small (Surface-Mount) part is wave-soldered; allow time for stress relaxation to occur. The majority of the drift will occur in the first 1000 hours at elevated temperatures ...
