This family is the analog thermometer of instruments, thermostats and teaching rigs since the 1980s: a three-terminal part that reads 10 millivolts per degree with no calibration - the LM35 in Celsius, the LM34 in Fahrenheit - plus the black-sheep member that shares the slope and nothing else, the LM335, whose Kelvin scale and two-terminal shunt behavior sit 3 volts above the others. The datasheets are siblings; the outputs are different worlds. Every substitution in this row that "reads offset by a fixed amount" is the scale, not the sensor, and the fix is arithmetic, not hardware.
The Common Grade of the Same Sensor
Shenzhen Spot Stock (24-48h Dispatch)
The everyday TO-92 grade of the Celsius sensor: 10mV per degree, 0V at 0C, about 250mV at 25C, 1.000V at 100C, factory calibrated with no external trim.
4V to 30V three-terminal supply; about 60uA quiescent, which keeps self-heating low.
The Kelvin Shunt - Three Volts and a Resistor Away
Shenzhen Spot Stock (24-48h Dispatch)
A different animal wearing a sibling number: a two-terminal shunt behaving like a temperature-sensitive zener at 10mV per KELVIN - about 2.982V at 25C - with a trim pin for one-point calibration.
Needs an external bias resistor (about 1mA) instead of drawing its own quiescent current; the shunt topology is the whole difference.
The Fahrenheit Sibling - Same Everything Else
Shenzhen Spot Stock (24-48h Dispatch)
The Fahrenheit scale of the same sensor design: 10mV per degree F, comparable accuracy class, same three-terminal simplicity and package family.
5V to 30V supply window - narrower than the LM35s.
Q: What is the difference between LM35 and LM335?
A: Scale and topology: LM35 reports Celsius at 10mV/degree from a three-terminal supply, about 250mV at 25C. LM335 reports Kelvin at 10mV/degree as a two-terminal shunt needing a bias resistor, about 2.982V at 25C. Same slope, 273 degrees and 3 volts apart.
Q: Can I use an LM335 where an LM35 was fitted?
A: The mechanical fit and the ADC wiring may pass, but the readings are Celsius-plus-273 on a 3V offset that many ADC references cannot span. It needs a firmware and reference re-plan - a design decision, not a parts substitution.
Q: Why does my temperature sensor read exactly 32 degrees high?
A: An LM34: the Fahrenheit-scale sibling of the LM35 reads 10mV per degree F, so the same code shows Fahrenheit values as if they were Celsius, offset and scaled. Read the part number off the body before calibrating anything.
It comes in a TO-46-3 metal can package with through-hole mounting, suited for board-level temperature monitoring where a direct analog voltage reading is preferred over a digital interface.
The TO-46-3 metal can is a hermetic package suited for environments where moisture or contamination is a concern. Through-hole mounting allows hand-solder or wave-solder assembly.
