GENERAL DESCRIPTION The REF01 precision voltage reference provides a stable 10 V
output that can be adjusted over a 3% range with minimal effect
on temperature stability. Single-supply operation over an input
voltage range of 12 V to 40 V, a 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
REF01 an excellent choice whenever a stable voltage reference is
required. Applications include DACs and ADCs, portable
instrumentation, and digital voltmeters. Full military
temperature range devices with screening to MIL-STD-883 are
available. For new designs, refer to ADR01.

ABSOLUTE MAXIMUM RATINGS
Table 5. Absolute maximum ratings apply to both DICE and 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 above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability
Table 6. Package Thermal Resistance 1 θJA is specified for worst-case mounting conditions, i.e., θJA is specified for
device in socket for TO, CERDIP, and PDIP packages θJA is specified for device
soldered to printed circuit board for SOIC package.
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.
