GENERAL DESCRIPTION  
The ADR290, ADR291 and ADR292 are low noise, micro-  
power precision voltage references that use an XFET reference  
circuit. The new XFET architecture offers significant perfor-  
mance improvements over traditional bandgap and Buried  
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.  
current is only 12 µA, making these devices ideal for battery-  
powered instrumentation. Three electrical grades are available  
offering initial output accuracies of 2 mV, 3 mV and 6 mV  
max for the ADR290 and ADR291, and 3 mV, 4 mV and  
6 mV max for the ADR292. Temperature coefficients for the  
three grades are 8 ppm/°C, 15 ppm/°C, and 25 ppm/°C max,  
respectively. Line regulation and load regulation are typically  
30 ppm/V and 30 ppm/mA, maintaining the reference’s overall  
high performance. For a device with 5.0 V output, refer to the  
ADR293 data sheet.  
®
The ADR29x family are series voltage references providing stable  
and accurate output voltages from supplies as low as 2.35 V for the  
ADR290. Output voltage options are 2.048 V, 2.5 V, and 4.096 V  
for the ADR290, ADR291, and ADR292 respectively. Quiescent  
The ADR290, ADR291, and ADR292 references are specified  
over the extended industrial temperature range of –40°C to  
+125°C. Devices are available in the 8-lead SOIC and 8-lead  
TSSOP packages.
