GENERAL DESCRIPTION
The ADR293-EP 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-EP 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. The temperature coefficient

is 30 ppm/°C maximum over the military temperature range,
and the initial error is only 0.2% at 25°C. Line regulation and
load regulation are typically 70 ppm/V and 30 ppm/mA,
respectively, maintaining the reference’s overall high
performance.
The ADR293-EP is specified over the military temperature
range of –55°C to +125°C. This device is available in an 8-lead
TSSOP package.
Additional applications information is available in the ADR293
data sheet.
