Analog Devices AD590 Temperature Transducer Datasheet
The AD590 temperature transducer from Analog Devices is a two‑terminal IC that outputs a current proportional to absolute temperature (PTAT). It operates from a wide supply range (+4 V to +30 V) and requires only a voltage supply, eliminating the need for external linearization or compensation circuitry.
The document includes detailed specifications, package options, application circuits, and thermal considerations, helping designers implement the device in remote sensing, temperature compensation, and control applications.
