The LM35DZ/NOPB from Texas Instruments is a precision integrated-circuit temperature sensor that is designed to provide superior performance over a wide range of temperatures. This product is an essential component for a variety of applications, including HVAC environmental controls, temperature monitoring systems, and thermal protection circuits. One of the key features of the LM35DZ/NOPB is its ability to produce an output voltage that is linearly proportional to the Celsius (Centigrade) temperature. This means that the sensor has a linear +10.0 mV/°C scale factor, which allows for easy temperature-to-voltage conversion. Moreover, the sensor does not require any external calibration to provide typical accuracies of ±1/4°C at room temperature and ±3/4°C over a full -55 to +150°C temperature range. The LM35DZ/NOPB is designed with low-output impedance, linear output, and precise inherent calibration, making interfacing to readout or control circuitry particularly easy. It can be used with single power supplies, or with plus and minus supplies, giving it versatility in different circuit designs. Another significant advantage of the LM35DZ/NOPB is its low power consumption. It draws less than 60 μA from the supply, which makes it highly suitable for battery-operated systems. Additionally, its low self-heating feature ensures that the sensor's accuracy is not affected by changes in ambient temperature. The LM35DZ/NOPB comes in a TO-92 package, a small and lightweight design that is easy to incorporate into a wide range of devices. This product is also RoHS compliant, meaning it adheres to the European Union's directive on the restriction of hazardous substances, making it an environmentally friendly choice. In summary, the LM35DZ/NOPB from Texas Instruments is a high-quality, reliable, and efficient temperature sensor. Its precision, versatility, low power consumption, and environmental compliance make it a leading choice for a wide range of temperature monitoring and control applications.
