AD590KF

AD590KF is a linear 1 microamp per kelvin output solid-state temperature sensor. This is a small temperature transducer that converts a temperature input into a proportional current output. The advanced technology is especially suited for special temperature measurement and control applications between -55 and 150°C when solid-state reliability, linearity, and accuracy are required. It can be used to determine minimum, average, and differential temperatures, in addition to being used for thermocouple cold junction compensation and temperature control applications. The size and responsiveness of make it perfect for uses where size is a consideration, such as on PC boards or heat sinks. Just power up and measure absolute temperature. Application includes ideal for fast response surface measurements, sensors for controllers and meters, use in custom-made probes, use on PC boards for accurate measurement.
