DESCRIPTION

The REF02 is a precision 5V voltage reference. The drift is

laser trimmed to 10ppm/°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. The REF02

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

with a very low current drain of 1mA, and excellent temperature

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. Available package options are DIP-8 and SO-8. The

REF02 is an ideal choice for portable instrumentation,

temperature transducers, Analog-to-Digital (A/D) and Digital-

to-Analog (D/A) converters, and digital voltmeters.

OUTPUT ADJUSTMENT The REF02 trim terminal can be used to adjust the voltage over a 5V ±150mV range. This feature allows the system designer to trim system errors by setting the reference to a voltage other than 5V, including 5.12V(1) for binary applications (see circuit on page 1). TYPICAL APPLICATIONS 2 VIN Adjustment of the output does not significantly affect the temperature performance of the device. The temperature coefficient change is approximately 0.7ppm/°C for 100mV of output adjustment. 0.
