Overview
The LM20CIM7 is a precision analog output CMOS integrated-circuit temperature sensor produced by Texas Instruments (formerly National Semiconductor). This sensor operates over a wide temperature range of −55°C to +130°C, making it suitable for various applications requiring accurate temperature measurement. The LM20CIM7 is powered by a supply voltage range of +2.4 V to +5.5 V and consumes a quiescent current of less than 10 µA, minimizing self-heating and power consumption.
