AD590MH/883B

The AD590MH/883B is a precision two-terminal integrated circuit temperature transducer from Analog Devices, qualified to the military screening standard MIL-STD-883 Class B. It produces an output current directly proportional to absolute temperature, scaled at 1 µA per Kelvin, enabling straightforward linear temperature-to-current conversion without complex signal conditioning. Operating from a supply range of 4 V to 30 V, the device maintains high linearity across a −55 °C to +150 °C temperature span, while the high-impedance current-loop output supports remote sensing over extended cable lengths without signal deterioration. The hermetic TO‑52 metal can package ensures long‑term stability and resilience in demanding environmental conditions.

Typical applications encompass industrial process control, thermal monitoring in avionics and ground‑defense electronics, cold‑junction compensation for thermocouple networks, and temperature‑compensated biasing of analog circuits. The /883B suffix designates compliance with full MIL‑STD‑883 screening, including burn‑in and hermeticity testing, suiting it for high‑reliability military and aerospace systems that require stringent traceability and extended service life. From a procurement standpoint, this military‑grade variant addresses long‑life program needs; sourcing typically involves verification of manufacturer certification, lot traceability, and conformance to applicable military standards to mitigate counterfeiting risks in legacy sustainment and new‑design high‑reliability platforms.
