LM235
LM235 is Precision temperature sensor manufactured by STMicroelectronics.
Features
- Directly calibrated in °K
- 1°C initial accuracy
- Operates from 450µA to 5m A
- Less than 1Ω dynamic impedance
Description
The LM135, LM235, LM335 are precision temperature sensors which can be easily calibrated. They operate as a 2-terminal Zener and the breakdown voltage is directly proportional to the absolute temperature at 10m V/°K.
The circuit has a dynamic impedance of less than 1Ω and operates within a range of current from 450µA to 5m A without alteration of its characteristics.
Calibrated at +25°C, the LM135, LM235, and LM335 have a typical error of less than 1°C over a 100°C temperature range. Unlike other sensors, the LM135, LM235, LM335 have a linear output.
