REF02APG4

Overview

The REF02APG4 is a precision voltage reference from Texas Instruments, delivering a fixed 5 V output. It features an initial accuracy of ±0.2% and a temperature coefficient of 15 PPM/°C. The device operates within a wide supply range up to 40 V maximum input voltage and supports a maximum shunt current of 21 mA. It functions reliably across an extended temperature range from -40°C to +85°C. The component draws a typical operating supply current of 1 mA and is housed in an 8-pin PDIP package.

Feature Summary

• Provides stable 5 V reference with high initial accuracy
• Operates over wide supply voltage range
• Low temperature drift for precision applications

Applications

• Precision analog-to-digital converter references
• Data acquisition systems
• Instrumentation circuits

Procurement Notes

Verify the specific suffix 'PG4' confirms the 8-pin PDIP package variant when sourcing. Confirm RoHS compliance status as indicated by the G4 suffix. Check manufacturer lifecycle status for availability constraints. Ensure the required ±0.2% accuracy grade matches design specifications. Validate package dimensions against PCB footprint requirements.

Selection Notes

Select this component when a fixed 5 V reference with ±0.2% initial accuracy is required. Consider the 15 PPM/°C temperature coefficient for thermal stability needs. Verify that the 21 mA maximum shunt current meets load requirements. Ensure the 8-pin PDIP package fits the assembly process. Compare against other REF02 grades if tighter accuracy is needed.

Part Context

Part of the REF02 series of precision voltage references. Designed for applications requiring stable voltage sources. Manufactured by Texas Instruments. Uses standard bipolar processes. Compatible with general-purpose analog circuit designs.

Replacement Considerations

Check REF02AUG4 for SOIC-8 surface mount equivalent. Verify REF02BPG4 for alternative grading options. Confirm pinout compatibility before substitution.
