LM335 - Precision Temperature Sensors

LM335 Precision Temperature Sensor - Easily Calibrated IC

The LM335 series offers precision, easily-calibrated integrated circuit temperature sensing. Designed to operate as a 2-terminal zener, it provides a breakdown voltage directly proportional to absolute temperature. This translates to a highly accurate +10 mV/˚K output. With a remarkably low dynamic impedance of less than 1Ω, the sensor maintains stable performance. It operates efficiently across a wide current range, from 400 µA to 5 mA. When calibrated at 25˚C, the LM335 typically exhibits less than 1˚C error over a 100˚C temperature span. A key advantage is its linear output, simplifying integration into various systems. This makes the LM335 an ideal choice for applications demanding reliable and accurate temperature measurement.
