Product Overview

The ADR291 series micropower low-noise precision Voltage Reference uses an XFET® reference circuit. The new XFET architecture offers significant performance improvements over traditional band gap and buried zener-based references. Improvements include one quarter the voltage noise output of band gap references operating at the same current, very low and ultra-linear temperature drift, low thermal hysteresis and excellent long-term stability. The ADR291 family is a series of voltage references providing stable and accurate output voltages. Quiescent current is only 12μA, making this device ideal for battery-powered instrumentation.
  • Pin-compatible with REF02/REF19x
  • 15μA Maximum supply current
  • 8 and 12μVp-p (0.1 to 10Hz) Low noise
  • 5mA High output current
  • 2.8 to 15V Supply range
