REF05

+5V Precision

VOLTAGE REFERENCE

(Guaranteed Long-Term Stability)

APPLICATIONS

q PRECISION REGULATORS

q CONSTANT CURRENT SOURCE/SINK

q DIGITAL VOLTMETERS

q A/D AND D/A CONVERTERS

q PRECISION CALIBRATION STANDARD

q TEST EQUIPMENT

DESCRIPTION

The REF05 is a precision 5V voltage reference. The

drift is laser trimmed to 8.5ppm/

°C max over the

extended industrial and military temperature range.

The REF05 provides a stable 5V output that can be

externally adjusted over a

±6% range with minimal

effect on temperature stability. REF05 operates from a

single supply with an input range of 8V to 40V with a

very low current drain of 1mA, and excellent tempera-

ture stability due to an improved design. Excellent line

and load regulation, low noise, low power, and low

cost make the REF05 the best choice whenever a 5V

voltage reference is required. The REF05 is an ideal

choice for portable instrumentation, temperature trans-

ducers, A/D and D/A converters, and digital voltmeter.
