REF02HJ

Overview

The REF02HJ is a precision voltage reference and temperature transducer manufactured by Analog Devices Inc. It provides a stable 5 V output with an initial accuracy of ±0.3% maximum. The device features a dedicated temperature monitoring pin that outputs a linear voltage proportional to absolute temperature, typically at 1.96 mV/°C for the J package. It operates over a wide input voltage range of 7 V to 40 V with a quiescent supply current of 1.4 mA maximum. The REF02HJ supports a load current of up to 10 mA and includes short-circuit protection. It is housed in an 8-lead TO-99 metal can package (J-Suffix) and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

Provides a precise 5 V bandgap reference output with low noise characteristics.
Includes a dedicated temperature monitoring pin for linear voltage output proportional to absolute temperature.
Features internal adjustment capability allowing output voltage trimming over a specified percentage range.
Designed with short-circuit proof output protection and requires no external components for basic operation.

Applications

Digital voltmeters
Portable instrumentation
Analog-to-digital converter (ADC) references
Digital-to-analog converter (DAC) references

Procurement Notes

Verify the specific suffix 'J' confirms the 8-lead TO-99 metal header package configuration. Confirm the operating temperature range aligns with system requirements (-40°C to +85°C). Ensure input voltage stays within the 7 V to 40 V limit. Check RoHS compliance status if required by assembly specifications. Validate pinout compatibility with existing PCB footprints for the J-Suffix package.

Selection Notes

Select this component when a stable 5 V reference is needed alongside integrated temperature sensing capabilities. The J package offers hermetic sealing suitable for harsh environments. Consider the 1.96 mV/°C temperature coefficient for thermal monitoring applications. Evaluate the 10 mA load driving capability against downstream circuit demands. Compare line regulation performance across the full 7 V to 40 V input range.

Part Context

The REF02 belongs to the REF01/REF02 family of precision bandgap voltage references from Analog Devices. While the REF01 provides a 10 V output, the REF02 variant delivers a 5 V output. This family is designed for applications requiring low drift, moderate accuracy, and low power consumption. The REF02HJ specifically denotes the high-accuracy version packaged in the TO-99 metal can format.

FAQ

How does the REF02HJ function as a temperature sensor?

Pin 3 provides a temperature voltage output that varies linearly with temperature. For the J package, the coefficient is approximately 1.96 mV/°C, with a voltage of about 550 mV at 25°C.
