REF02EP+

Overview

The REF02EP+ is a precision voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-pin Plastic DIP package. It provides a nominal output voltage of 5V with a maximum temperature coefficient of 8.5 ppm/°C and an initial error of ±15mV. The device operates within a temperature range of 0°C to +70°C and supports single-supply operation over an input voltage range of 7V to 33V. It features a low quiescent current drain of 1mA and includes a dedicated TEMP pin for linear temperature sensing applications.

Feature Summary

• Provides a stable 5V output suitable for high-precision analog circuits
• Includes a dedicated temperature voltage output pin for sensing applications
• Features short-circuit protection for indefinite duration safety

Applications

• Analog-to-Digital Converters
• Digital-to-Analog Converters
• Precision Temperature Transducers

Procurement Notes

Verify the component designation against official manufacturer documentation to confirm the specific suffix indicates a lead-free package variant. Ensure that the ordering information matches the required operating temperature range and package type specifications before procurement.

Selection Notes

Select this component when a fixed 5V reference with integrated temperature sensing capabilities is required. Consider the 8.5 ppm/°C temperature stability and 1mA current consumption for power-sensitive designs. Verify compatibility with the 7V to 33V input supply range and 8-pin DIP footprint constraints.

Part Context

This part belongs to the industry-standard REF01/REF02 series of precision voltage references. The REF02 variant specifically targets 5V applications, while the REF01 offers a 10V output. Both devices share similar architectural characteristics but differ in nominal output levels and adjustment ranges.
