The LM35DZ is a simple temperature sensor IC for projects that need low-cost temperature measurement with good accuracy around room temperature.
It is suited to remote sensing applications and runs from a broad 4 to 30 V supply range, with very low current drain to help minimise self-heating.
Its low impedance output makes it practical to interface with measurement circuits or microcontroller analogue inputs in embedded electronics projects.
Features:
- 0.5°C Ensured Accuracy (+25°C)
- Suitable for Remote Applications
- Low Cost Due to Wafer-Level Trimming
- Operates from 4 to 30 V
- Less than 60-μA Current Drain
- Low Self-Heating, 0.08°C in Still Air
- Low Impedance Output, 0.1 Ω for 1 mA Load
Jargon buster
Plain-language definitions for the technical terms used above.
- Impedance
- Impedance is the total opposition a component or circuit presents to alternating current, measured in ohms, combining resistance with frequency-dependent reactance. It appears in many contexts, such as matching a speaker's impedance (for example 4 ohm or 8 ohm) to an amplifier or the input and output impedance of signal circuits, and a correct match helps avoid weak signals, distortion or damage.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
