1-µA/K IC Temperature-to-Current Transducer

At $1.95 in 100's, 2-Terminal AD590J is Easy to Choose & Use; Temperature -55°C to 150°C, Linearity error to 0.5°C

The AD590, a two-terminal monolithic-IC temperature transducer, produces an output current that is proportional to absolute temperature ("PTAT"). The device acts as a high-impedance constant-current regulator, passing 1µA/K; performance is essentially independent of terminal voltage, from +4V to +30V. Read full article
