REF01EP+

Overview

The REF01EP+ is a precision voltage reference IC from the REF01/REF02 series, manufactured by Analog Devices Inc./Maxim Integrated. It provides a stable +10V output with an initial error of ±30mV and a maximum temperature coefficient of 8.5ppm/°C. The device operates within a temperature range of 0°C to +70°C using a single supply voltage between 13V and 33V. It features a low quiescent current drain of approximately 1mA and includes a trim terminal for output adjustment over a ±6% range without significantly affecting temperature stability. The component is housed in an 8-pin Plastic DIP package.

Feature Summary

• Industry-standard precision voltage reference with pretrimmed +10V output
• Excellent temperature stability with a typical coefficient of 3ppm/°C
• Low noise performance suitable for sensitive analog applications
• Integrated short-circuit protection for enhanced reliability

Applications

• Analog-to-Digital Converters
• Digital-to-Analog Converters
• Digital Voltmeters
• Voltage Regulators
• Threshold Detectors

Procurement Notes

Verify the specific suffix 'EP+' against the manufacturer's official datasheet to confirm lead-free status and exact electrical tolerances. Ensure the ordering code matches the required 8-pin Plastic DIP package configuration. Cross-reference the part number with the latest product change notices to confirm availability and any potential pinout or specification updates before finalizing procurement.

Selection Notes

Select this component when a stable +10V reference is required for systems operating between 0°C and +70°C. The REF01EP+ offers a balance of high precision and low power consumption, making it suitable for battery-operated or thermally constrained environments where strict accuracy is needed. Consider the trim capability if system-level calibration is necessary to compensate for board-level errors.

Part Context

The REF01EP+ belongs to the REF01/REF02 family of precision voltage references designed for general-purpose use. This series is characterized by its ability to provide stable reference voltages with minimal drift over temperature variations. The REF01 variant specifically targets applications requiring a +10V output, distinguishing it from the +5V REF02 model which also includes a temperature sensing feature on the TEMP pin.
