Texas Instruments LM335Z Precision Temperature Sensor TO92

The Texas Instruments LM335Z/NOPB is a precision integrated circuit temperature sensor, designed for accuracy and ease of use. It operates as a two-terminal zener, with a breakdown voltage that is directly proportional to absolute temperature at a rate of 10 millivolts per degree Kelvin. This linear relationship between voltage and temperature makes it exceptionally straightforward to integrate into a wide range of electronic designs.

One of the key advantages of this sensor is its excellent performance across a broad operating current. With a dynamic impedance of less than 1 ohm, it operates reliably over a current range of 400 microamperes to 5 milliamps with virtually no change in its characteristics. This low impedance, combined with its linear output, simplifies the process of interfacing with readout or control circuitry, eliminating the need for complex linearisation circuits.

Calibration is remarkably 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. It is directly calibrated to the Kelvin temperature scale, offering an initial accuracy of 1°C. The sensor features a wide operating temperature range and can withstand an over-range of 200°C, making it suitable for demanding environments.
