DESCRIPTION sensing. The LM234-3 and LM234-6 are specifiedasThe LM134/LM234/LM334 are 3-terminal adjustable true temperature sensors with ensured initialcurrent sources featuring 10,000:1 rangein operating accuracy of ±3°C and ±6°C, respectively. Thesecurrent, excellent current regulation anda wide devices are ideal in remote sense applicationsdynamic voltage range of 1V to 40V. Currentis because series resistancein long wire runs does notestablished with one external resistor and no other affect accuracy.In addition, only2 wires are required.parts are required. Initial current accuracyis ±3%.
