GENERAL DESCRIPTION
The ADR290, ADR291 and ADR292 are low noise, micropower precision voltage references that use an XFET™ reference circuit. The new XFET architecture offers significant performance improvements over traditional bandgap and Zener-based references. Improvements include: one quarter the voltage noise output of bandgap references operating at the same current, very low and ultralinear temperature drift, low thermal hysteresis and excellent long-term stability.

   Voltage Options 2.048 V, 2.500 V and 4.096 V
   2.7 V to 15 V Supply Range
   Supply Current 12 mA max
   Initial Accuracy 62 mV max
   Temperature Coefficient 8 ppm/8C max
   Low-Noise 6 mV p-p (0.1 Hz–10 Hz)
   High Output Current 5 mA min
   Temperature Range 2408C to 11258C
   REF02/REF19x Pinout

APPLICATIONS
   Portable Instrumentation
   Precision Reference for 3 V and 5 V Systems
   A/D and D/A Converter Reference
