GENERAL DESCRIPTION

The REF02 precision voltage reference provides a stable 5 V
output that can be adjusted over a ±6% range with minimal
effect on temperature stability. Single-supply operation over an
input voltage range of 7 V to 40 V, low current drain of 1 mA,
and excellent temperature stability are achieved with an
improved band gap design. Low cost, low noise, and low power
make the REF02 an excellent choice whenever a stable voltage
reference is required. Applications include DACs and ADCs,
portable instrumentation, and digital voltmeters. The versatility
of the REF02 is enhanced by its use as a monolithic temperature
transducer. For new designs, refer to ADR02.

ABSOLUTE MAXIMUM RATINGS
Table 5.
Table 6. Package Thermal Resistance

*θJA is specified for worst-case mounting conditions, i.e. ,θJA is specified for
device in socket for TO, CERDIP, PDIP, and LCC packages; θJA is specified for
device soldered to printed circuit board for SOIC packages.
Absolute maximum ratings apply to both DICE packaged parts,
unless otherwise noted.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions outside of those indicated in the operation
sections of this specification is not implied. Exposure to
absolute maximum ratings for extended periods may affect
device reliability.
ESD CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product 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.
