Thermometer (LM3911, -20 bis +50 Grad Celsius)

Using the 3½-digit-A/D-converter LD l l 0/ 111 and a minimum of external components, it is possible to construct a universal digital voltmeter. The accuracy of the meter is approx. 0.05% + l digit. The scale of the meter runs from -2 V ... +2 V and by means of additional voltage dividers can be extended as required.
