Texas Instruments LM335Z Precision Temperature Sensor TO92

The Texas Instruments LM335Z Precision Temperature Sensor TO92 is a precision integrated circuit temperature sensor with a voltage output that is directly proportional to absolute temperature at 10 mV per degree Kelvin.

Overview

The LM335Z operates as a two-terminal zener, with a breakdown voltage that varies linearly with absolute temperature. This linear relationship between voltage and temperature makes it straightforward to integrate into a wide range of electronic designs. The sensor is directly calibrated to the Kelvin temperature scale.

Key Features

The sensor operates across a broad current range of 400 µA to 5 mA, with a dynamic impedance of less than 1 Ω. This low impedance and linear output simplify interfacing with readout or control circuitry, reducing the need for complex linearisation circuits.

Calibration and Operating Range

Calibration is simple. When calibrated at a single temperature point of 25°C, the device typically maintains an error of less than 1°C across a 100°C temperature range. The sensor has a sensing temperature range of -40°C to +100°C and can withstand an over-range of 200°C, making it suitable for demanding environments.
