GENERAL DESCRIPTION  
The ADR293 is a low noise, micropower precision voltage  
reference that utilizes an XFET (eXtra implanted junction  
GND

™

FET) reference circuit. The new XFET architecture offers sig-  
nificant 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.

The ADR293 is a series voltage reference providing stable and  
accurate output voltage from a 6.0 V supply. Quiescent current  
is only 15 µA max, making this device ideal for battery powered  
instrumentation. Three electrical grades are available offering  
initial output accuracy of ±3 mV, ±6 mV, and ±10 mV. Tem-  
perature coefficients for the three grades are 8 ppm/°C, 15 ppm/°C  
and 25 ppm/°C max. Line regulation and load regulation are typi-  
cally 30 ppm/V and 30 ppm/mA, maintaining the reference’s over-  
all high performance.

The ADR293 is specified over the extended industrial tempera-  
ture range of –40°C to +125°C. This device is available in the  
8-lead SOIC, 8-lead TSSOP and the TO-92 package.
