REF02DH

Overview

The REF02DH is a precision voltage reference IC manufactured by Analog Devices Inc., housed in an 8-lead TO-5 metal can package. It provides a fixed nominal output voltage of 5V with a guaranteed accuracy of ±1% over the specified temperature range. The device operates within an input voltage range of 7V to 40V and draws a maximum quiescent supply current of 2mA. It features a dedicated temperature output pin that delivers a linear voltage proportional to absolute temperature, facilitating integrated thermal monitoring capabilities.

Feature Summary

• Provides stable 5V output with low drift characteristics suitable for precision applications
• Includes a dedicated temperature output pin for linear voltage proportional to absolute temperature
• Offers high line rejection and low noise performance for sensitive signal processing

Applications

• A/D and D/A converters
• Precision regulators
• Constant current sources
• Bridge excitation circuits

Procurement Notes

Verify the specific suffix DH indicates the 8-lead TO-5 metal can package configuration. Confirm the operating temperature range is 0°C to 70°C as per the datasheet specifications for this variant. Ensure compatibility with existing leaded mounting requirements before procurement.

Selection Notes

Select this component when a hermetic metal can package is required for environmental protection or specific mechanical constraints. It is appropriate for designs needing a fixed 5V reference with moderate accuracy and integrated temperature sensing without external components.

Part Context

This part belongs to the REF-01/REF-02 series of precision bandgap voltage references. The series includes variants offering 10V and 5V outputs with varying accuracy grades and package options including plastic DIP, CERDIP, and metal cans. The REF-02 specifically adds a temperature output feature not present in the REF-01.
