Overview
The EL2228CS is a dual low-noise voltage feedback operational amplifier manufactured by Elantec Semiconductor. It features a bandwidth of 80 MHz at unity gain and a gain-bandwidth product of 40 MHz. The device operates on supply voltages ranging from ±2.5V to ±12V with a total supply current of 5mA for both channels. Key electrical parameters include an input offset voltage of 200 µV, input bias current of 4.5 µA, slew rate of 65V/µs, and output current per channel of 180 mA. It is housed in an 8-SOIC package.
Feature Summary
- Dual-channel architecture designed for low-noise signal processing applications
- High-speed performance with 80 MHz bandwidth and 65V/µs slew rate
- Low power consumption requiring only 4.5mA per amplifier
- Unity-gain stable operation suitable for direct filtering integration
Applications
- ADSL filter circuits
- HDSLII filter designs
- Ultrasound input amplification
- Wideband instrumentation systems
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.
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.
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.
Replacement Considerations
Public confirmed substitute part number: AD8512ARZ.
