The LM20BIM7X/HALF is a precision analog output CMOS integrated-circuit temperature sensor that operates over 55°C to 130°C. The power supply operating range is 2.4 V to 5.5 V. The transfer function of LM20BIM7X/HALF is predominately linear, yet has a slight predictable parabolic curvature. The accuracy of the LM20BIM7X/HALF when specified to a parabolic transfer function is ±1.5°C at an ambient temperature of 30°C. The temperature error increases linearly and reaches a maximum of ±2.5°C at the temperature range extremes. The temperature range is affected by the power supply voltage. At a power supply voltage of 2.7 V to 5.5 V, the temperature range extremes are 130°C and 55°C. Decreasing the power supply voltage to 2.4 V changes the negative extreme to 30°C, while the positive extreme remains at 130°C.
The LM20BIM7X/HALF quiescent current is less than 10 μA. Therefore, self-heating is less than 0.02°C in still air. Shutdown capability for the LM20BIM7X/HALF is intrinsic because its inherent low power consumption allows it to be powered directly from the output of many logic gates or does not necessitate shutdown.
