Description

The LM35CAZ is a precision temperature sensor from Texas Instruments, designed to measure temperature with a linear output voltage that is directly proportional to the Celsius temperature. This sensor offers high accuracy and a wide operating temperature range, typically from -55°C to +150°C. It provides a linear scale factor of 10mV/°C, making it straightforward to interface with analog and digital systems.
The LM35CAZ requires no external calibration or trimming to maintain an accuracy of ±0.2°C at room temperature and ±0.4°C over a broader range, making it suitable for a variety of applications, including environmental monitoring, consumer electronics, and industrial systems. Its design ensures low self-heating, reducing errors in temperature measurement.
The device operates with a supply voltage range of 4V to 30V and has a low current consumption, making it energy-efficient. Its TO-92 package allows for easy mounting on PCBs, and the sensor's three-pin configuration simplifies integration into electronic circuits.
