AD590 is a two-terminal integrated circuit temperature transducer that produces an output current proportional to absolute temperature. It features linear current output, wide temperature range, probe compatibility, voltage input/current output, etc.
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.
| Linear Current Output | 1 pA/K |
|---|---|
| Calibration Error @ +25 °C | +5.0 °C (AD590J/K) / +2.5 °C (AD590M) |
| Power Supply Rejection (4 V to 5 V) | 0.5 pA/V |
| Case Isolation to Either Lead | 10 MΩ |
The calibration error at +25 °C is +5.0 °C for the AD590J version and +2.5 °C for the AD590M version.
