Overview
The REF02HJ8 is a precision 5V bandgap voltage reference housed in an 8-lead CERDIP package. It provides stable output voltages with a typical temperature coefficient of 5ppm/°C and low noise characteristics. The device includes a dedicated temperature output pin that delivers a linear voltage proportional to absolute temperature, facilitating thermal monitoring. It operates within a supply voltage range of 7V to 40V and supports a maximum load current of 10mA. The component is designed for applications requiring moderate accuracy and low power consumption.
Feature Summary
- Includes a dedicated temperature output pin providing a linear voltage proportional to absolute temperature
- Features low drift performance with a typical temperature coefficient of 5ppm/°C
- Offers high line rejection and low noise characteristics for stable operation
Applications
- A/D and D/A Converters
- Precision Regulators
- Constant Current Sources
- Bridge Excitation
Procurement Notes
Verify the specific suffix HJ8 corresponds to the 8-lead CERDIP package and the required operating temperature range. Confirm lead finish specifications if RoHS compliance is mandatory for the target assembly process. Ensure input voltage constraints are respected during system design to maintain regulation integrity.
Selection Notes
Select this component when a fixed 5V reference with integrated temperature sensing is required. It is suitable for designs prioritizing low drift and moderate accuracy over ultra-high precision. Consider the CERDIP package for hermetic sealing requirements or specific mounting constraints compared to plastic DIP alternatives.
Part Context
This part belongs to the REF-01/REF-02 series of precision voltage references manufactured by Analog Devices (formerly Linear Technology). The series offers both 10V and 5V options with various package configurations including metal cans, plastic DIPs, and ceramic DIPs. The REF-02 variant specifically adds the temperature output capability not present in the REF-01 model.

FAQ
What is the function of Pin 3 on the REF02HJ8?
Pin 3 serves as the temperature output, providing a linear voltage proportional to absolute temperature.
Is the REF02HJ8 compatible with the REF-01?
They share similar pinouts and functionality, but the REF-01 lacks the temperature output pin found on the REF-02.
