illustrate

The LM20 is a sophisticated analog output CMOS integrated circuit temperature sensor with a temperature range of -55°C to +130°C. The supply operates with a transfer function of +2.4 V to +5.5 V in the LM20 predominantly straight line, but with a slight predictable parabolic curvature. The LM20 is accurate when paraboling, specifying a transfer function of ± 1.5°C +30°C for ambient temperature The temperature error increases linearly and reaches the maximum in the extreme temperature range of ± 2.5 °C. The temperature range is dependent on the supply voltage. Extreme temperatures in the supply voltage range from 2.7 V to 5.5 V are +130°C and -55°C The negative extreme to the power supply voltage is reduced to 2.4 to -30 ° C, while still actively at +130 ° C

The LM20 has a quiescent current of less than 10 microamps. Therefore, self-heating is less than 0.02 °C in still air. The ability to shut down for the LM20 is intrinsic because its inherently low power consumption allows it to be output directly by many logic gates or without the need to be shut down.
