Procurement Notes

Verify the specific suffix AGS corresponds to the 8-lead MSOP package and ±0.08% accuracy grade when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact manufacturer designation to avoid pinout or electrical specification mismatches during integration.

Selection Notes

Select this component when a fixed 2.5V reference with superior initial accuracy compared to standard grades is required. The low quiescent current makes it ideal for energy-constrained designs. Consider the thermal performance and package size constraints relative to other REF19x variants if higher current or different voltage outputs are needed.

Part Context

This part belongs to the REF19x series of precision micropower voltage references from Analog Devices. The series offers various accuracy grades and output voltages, utilizing proprietary trimming technologies to ensure low temperature coefficients and long-term stability. The REF192 variant specifically targets applications needing reliable 2.5V references with minimal power draw.

Replacement Considerations

The ADR3625 serves as a functional replacement offering similar voltage output but with improved accuracy grades and higher output current capacity. Verify pin compatibility and thermal characteristics before substitution.
