Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify component authenticity through authorized distributors as the EL2228CS may be discontinued or obsolete. Confirm RoHS compliance status and check for valid replacement part numbers such as AD8512ARZ if sourcing new inventory. Ensure datasheet revisions match design requirements before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring low noise specifications of 4.9nV/√Hz voltage noise. Consider the 8-SOIC package constraints and operating temperature range of -40°C to 85°C. Verify that the ±2.5V to ±12V supply range aligns with system power rails and that the 180mA output current meets load drive requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

The EL2228CS belongs to the EL2228 family of dual low-noise amplifiers originally developed by Elantec Semiconductor. This series is engineered for high-fidelity analog signal conditioning where minimal noise addition is critical. The CS suffix typically denotes the specific surface-mount SOIC packaging variant within the broader product line.
