Product Overview

AD590 is a 2-terminal integrated circuit temperature transducer that produces an output current proportional to absolute temperature. This device acts as a high impedance, constant current regulator passing 1μA/K. Laser trimming of the chip’s thin-film resistors is used to calibrate the device to 298.2μA output at 298.2K (25°C). It should be used in any temperature-sensing application below 150°C in which conventional electrical temperature sensors are currently employed. This inherent low cost of a monolithic integrated circuit combined with the elimination of support circuitry makes the AD590 an attractive alternative for many temperature measurement situations. In addition to temperature measurement, applications include temperature compensation or correction of discrete components, biasing proportional to absolute temperature, flow rate measurement, level detection of fluids and anemometry. It is particularly useful in remote sensing applications.
  • Insensitive to voltage drops over long lines due to its high impedance current output
  • Output characteristics also makes easy to multiplex
  • Current can be switched by CMOS multiplexer or supply voltage can be switched by logic gate output
  • Probe compatible ceramic sensor package, sensor isolation from case
  • Wide power supply range from 4V to 30V
  • Nominal current output at 25°C is 298.2µA
  • Temperature range from -55°C to 150°C
  • 3-Pin TO-52 package
  • High output impedance (10Mohm) provides excellent rejection of supply voltage drift
