High precision extreme temperature voltage reference for mining, drilling and avionic applications
ADI’s ADR225 is an extreme temperature precision 2.5V band gap voltage reference with an upper temperature range of 175C and 210C. The device is available now from Digi-Key. It has high output current at 10mA and requires up to 50µA maximum supply current. It can use a wide supply voltage range from 3.3V to 16V.
These devices are ideal for applications that require precision reference in a high temperature environment such as drilling and avionics. The device comes in both an eight-lead SOIC and an eight-lead ceramic flat pack (FLATPACK). The SOIC has an upper temperature range of +175C and the FLATPACK is at +210C.
