LM35DZ Precision Temperature Sensor IC

The LM35DZ Precision Temperature Sensor IC is a high-accuracy analog temperature sensor designed to provide a linear voltage output directly proportional to the temperature in degrees Celsius. With factory trimming and calibration at the wafer level, this IC offers excellent linearity and accuracy without the need for any external calibration or signal conditioning.

Unlike sensors calibrated in Kelvin, the LM35DZ provides direct Centigrade readings, making it more intuitive and easier to interface with ADCs and microcontroller systems. It has low self-heating, operates from a wide voltage range, and is suitable for a variety of temperature monitoring applications such as HVAC systems, consumer electronics, and industrial controls.
