DESCRIPTION

The REF02 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 REF02 provides a stable 5V output that can be

externally adjusted over a ±6% range with minimal

effect on temperature stability. REF02 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 REF02 the best choice whenever a 5V

voltage reference is required. All popular package

options are available: plastic DIP, and SOIC. The

REF02 is an ideal choice for portable instrumentation,

temperature transducers, A/D and D/A converters, and

digital voltmeter.
