LM35DMX

The Texas Instruments LM35DMX is an analog temperature sensor designed for precise temperature measurements. It features a linear output voltage that is directly proportional to the Centigrade temperature, with a scale factor of 10mV/°C. This simplifies interfacing with readout or control circuitry as no large constant voltage subtraction is required for Centigrade scaling.

The device is rated for a wide operating temperature range of -55°C to 150°C, making it suitable for diverse environmental conditions. It operates from a supply voltage of 4V to 30V and draws a low supply current of less than 60µA, minimizing self-heating effects. The LM35DMX offers ensured accuracy of ±0.5°C at 25°C and ±1.5°C over its full operating range, with typical non-linearity of only ±¼°C.

Packaged in an 8-SOIC surface mount package, the LM35DMX is designed for easy integration into printed circuit boards. It is supplied on tape and reel, with a reel diameter of 330mm and a reel width of 12.4mm, facilitating automated assembly processes. The low-impedance output and inherent calibration at the wafer level contribute to its cost-effectiveness and ease of use in remote applications.

This sensor is UL recognized and is well-suited for applications requiring accurate and reliable temperature monitoring. Its analog output and straightforward operation make it a versatile component for embedded systems, industrial controls, and consumer electronics.
