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.
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

current is only 12
μ
A, 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 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.
