NS LM20CIM7X

Overview

The LM20CIM7X 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 LM20CIM7X is predominately linear, yet has a slight predictable parabolic curvature. The accuracy of the LM20CIM7X 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 LM20CIM7X quiescent current is less than 10 μA. Therefore, self-heating is less than 0.02°C in still air. Shutdown capability for the LM20CIM7X 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.
