Lm235a ± 1 ° C analog output temperature sensor, military grade, airtight to package

LM135 series is a precise and easy to calibrate integrated circuit temperature sensor. As a double ended zener diode, the breakdown voltage of LM135 is proportional to the absolute temperature at 10 MV / ° K. The dynamic impedance of the device is less than 1 Ω, and the working current range is 400 μ A to 5 mA with little change in performance. When calibrated at 25 ° C, the error of LM135 within the temperature range of 100 ° C is usually less than 1 ° C. Unlike other sensors, the LM135 has a linear output. LM135 applications include almost any type of temperature detection, with a temperature range of -55 ° C to 150 ° C. Low impedance and linear output make it particularly easy to interface with readout or control circuits. The LM135 operating temperature range is -55 ° C to 150 ° C, while the lm235 operating temperature range is?? Temperature range from 40 ° C to 125 ° C. The operating temperature range of lm335 is -40 ° C to 100 ° C. Lmx35 devices are packaged with sealed to transistors, while lm335 is also directly calibrated to Kelvin temperature of 1 ° C with plastic packaging characteristics. The initial accuracy operating current range is 400 μ A to 5 Ma less than 1 Ω dynamic impedance easy calibration wide operating temperature range 200 ° C super range low cost
