2-Terminal Temperature-to-Current Thermometer Suitable for Use at the End of Long Wire Runs

Apr 22nd 2009
By adding the LT3092 to a thermistor kit along with three 0.1% accuracy resistors and one final trim, a very accurate 2-terminal temperature-to-current converter can be built. This circuit measures 700μA operating current at 0°C, dropping by 2μA every degree until 100°C, at which point the current measures 500μA. The obvious ...
