Overview
The REF02EH is a precision voltage reference providing a fixed 5V output with ±0.3% initial accuracy and a typical temperature coefficient of 5ppm/°C. It operates within an input voltage range of 7V to 40V, drawing a maximum quiescent supply current of 1.4mA. The device features a dedicated temperature output pin generating a linear voltage proportional to absolute temperature. It is housed in an 8-lead TO-5 metal can package and is guaranteed for operation over the 0°C to 70°C temperature range.
Feature Summary
- Provides stable 5V bandgap reference output with low drift characteristics
- Includes a dedicated temperature output pin for linear voltage proportional to absolute temperature
- Features high line rejection and low noise performance
- Designed for applications requiring moderate accuracy and low power consumption
Applications
- A/D and D/A converters
- Precision regulators
- Constant current sources
- Bridge excitation circuits
Procurement Notes
Verify the specific ordering suffix EH corresponds to the 8-lead TO-5 metal can package and the 0°C to 70°C operating temperature range. Confirm that the component meets lead-free finish requirements if applicable to your assembly process. Ensure the input voltage does not exceed the absolute maximum ratings during operation.
Selection Notes
Select this component when a fixed 5V precision reference is required alongside temperature sensing capabilities. It is suitable for designs prioritizing low power consumption and moderate accuracy. Consider the TO-5 package constraints for thermal management and board space. Compare against higher accuracy alternatives like the LT1019 if tighter specifications are needed.
Part Context
The REF02EH belongs to the REF-01/REF-02 series of precision voltage references manufactured by Analog Devices (formerly Linear Technology). This series utilizes bandgap technology to deliver stable outputs. The REF-02 variant specifically includes a temperature output feature, distinguishing it from the REF-01. The 'E' suffix denotes the commercial temperature grade.
Replacement Considerations
The REF02HH is a compatible alternative within the same series offering similar electrical characteristics but potentially different manufacturing lot details. Verify pin compatibility and package dimensions before substitution.
