GENERAL DESCRIPTIONThe ADR293 is a low noise, micropower precision voltage
reference that utilizes an XFET™ (eXtra implanted junction
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.

WAFER TEST LIMITSNOTES
Electrical tests are performed as wafer probe to the limits shown. Due to variations in assembly methods and normal yield loss, yield after packaging is not guaranteed
for standard product dice. Consult factory to negotiate specifications based on dice lot qualification through sample lot assembly and testing.

NOTE
1Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
CAUTIONESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the ADR293 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
NOTEθJA is specified for worst case conditions, i.e., θJA is specified for device in socket
for PDIP, and θJA is specified for a device soldered in circuit board for SOIC
packages.
