REF02EP-G107

Overview

The REF02EP-G107 is a precision series voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 5V with an initial accuracy tolerance of ±0.06%. The device features a temperature coefficient of 8.5ppm/°C and operates within a supply voltage range of 13V to 33V. It draws a supply current of 1.4mA and supports a maximum output current of 21mA. The component is housed in an 8-DIP package (0.300 inch, 7.62mm width) and is rated for operation between -55°C and +125°C.

Feature Summary

• Provides a stable fixed 5V output suitable for high-precision analog circuits
• Features low temperature drift characteristics for consistent performance across wide thermal ranges
• Designed for robust operation with high input voltage headroom

Applications

• Precision data acquisition systems requiring stable reference voltages
• High-resolution analog-to-digital converter (ADC) front-ends
• Industrial instrumentation and sensor signal conditioning

Procurement Notes

Verify the specific suffix G107 against official manufacturer documentation to confirm pinout compatibility and exact electrical tolerances. Ensure the procurement channel sources genuine components from Analog Devices or Maxim Integrated to avoid counterfeit parts. Confirm that the 8-DIP package style matches the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when a fixed 5V reference is required with moderate temperature stability. It is appropriate for applications where the input supply voltage exceeds 13V. Consider alternative packages if surface-mount technology is preferred, as this part utilizes a through-hole DIP configuration. Evaluate power dissipation requirements given the 1.4mA quiescent current and potential load currents up to 21mA.

Part Context

The REF02 belongs to the Maxim Integrated REF01/REF02 family of precision voltage references. These devices are designed to offer better performance than standard zener diodes while maintaining simplicity. The REF02 specifically targets applications needing higher output voltages compared to the REF01 series, typically utilizing internal bandgap and zener technologies to achieve specified accuracy and drift characteristics.
