LM35DZ Precision Centigrade Temperature Sensor – TO‑92 Package

The LM35DZ is a precision analog temperature sensor that provides a voltage output linearly proportional to the temperature in degrees Celsius (10 mV/°C). It operates from a single power supply and does not require external calibration or trimming. With its wide supply voltage range and very low self‑heating, the LM35DZ is ideal for embedded systems, microcontroller-based projects (Arduino, Raspberry Pi), HVAC systems, battery monitoring, and general temperature sensing applications. It comes in a TO‑92 through‑hole package, making it easy to mount on a PCB. The device maintains high accuracy over a broad temperature range and draws minimal current, ensuring minimal impact on the system it monitors.

Key Features:

• Calibrated directly in Celsius (Centigrade) for ease of use.
• Linear scale factor of 10 mV per °C – output voltage = 10 mV × temperature in °C.
• Wide supply voltage range: from 4 V to 30 V.
• Very low quiescent current (typically less than 60 µA) minimizing self‑heating.
• Accuracy: approximately ±0.5 °C at 25 °C; wide temperature operation from −55 °C to +150 °C.
• Through‑hole TO‑92 package for easy PCB mounting and prototyping.
