LM35DZ | Precision Temperature Sensor IC

The LM35DZ is a precision integrated-circuit temperature sensor from Texas Instruments. It provides an analog output voltage linearly proportional to the temperature in °C, making it ideal for accurate temperature monitoring without additional calibration.

Key Features

• Linear voltage output directly proportional to Centigrade temperature

• No need to subtract a large constant voltage for Centigrade scaling

• Typical accuracy: ±¼°C at room temperature

• Full temperature range accuracy: ±¾°C from -55°C to 150°C

• No external calibration or trimming required

• Low-cost solution due to wafer-level trimming and calibration

Typical Applications

• Temperature monitoring in industrial and consumer electronics

• HVAC systems and thermostats

• Over-temperature protection circuits

• Embedded systems and microcontroller-based projects
