GENERAL DESCRIPTION
The ADR293 is a low noise, micropower precision voltage
reference that utilizes an XFET® (eXtra implanted junction FET)
reference circuit. The 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 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 maximum, 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.
Temperature coefficients for the three grades are 8 ppm/°C,

15 ppm/°C, and 25 ppm/°C maximum. Line regulation and load
regulation are typically 30 ppm/V and 30 ppm/mA, respectively,
maintaining the reference’s overall high performance.
The ADR293 is specified over the extended industrial
temperature range of –40°C to +125°C. This device is available
in the 8-lead SOIC and 8-lead TSSOP packages.
