ANALOG DEVICES ADR440/ADR441/ADR443/ADR444/ADR445 handbook (1)
The ADR44x family of XFET voltage references offers ultralow noise (0.1 Hz to 10 Hz) and superb temperature stability, with A‑grade parts achieving 10 ppm/°C and B‑grade parts 3 ppm/°C. They operate from 3 V to 18 V supply voltage, feature a low dropout of 500 mV, and can source up to +10 mA or sink up to –5 mA.
These devices are intended for precision data‑acquisition systems, high‑resolution converters, battery‑powered instrumentation, medical instruments, and industrial process control. The series is available in 8‑lead SOIC and MSOP packages and is rated for –40 °C to +125 °C operation.
