EL2228CS

Overview

The EL2228CS is a dual low-noise voltage feedback operational amplifier manufactured by Renesas Electronics Corporation. It features an input offset voltage of 3mV, supply current of 5mA per channel, and a -3dB bandwidth of 80MHz at unity gain. The device operates on dual supplies ranging from ±2.5V to ±12V with a maximum total span of 24V. It provides a slew rate of 65V/µs and a gain-bandwidth product of 40MHz. The component is housed in an 8-SOIC package and supports operation within a temperature range of -40°C to +85°C.

Feature Summary

Dual-channel architecture designed for filtering applications requiring minimal noise processing.
Voltage feedback topology enabling stability with capacitive feedback elements for active filters.
Low power dissipation characteristics suitable for space-constrained designs.

Applications

ADSL filter circuits
HDSLII filter circuits
Ultrasound input amplifiers
Wideband instrumentation systems

Procurement Notes

Verify the specific manufacturer origin as the EL2228 was originally developed by Intersil before corporate acquisition. Confirm RoHS compliance status and lead-free plating specifications against the latest datasheet revision. Ensure the 8-SOIC package dimensions match the required PCB footprint constraints for the target assembly process.

Selection Notes

Select this component when low voltage and current noise are critical requirements for signal integrity. The voltage feedback structure is preferred over current-feedback types when standard feedback networks or capacitors are necessary. Verify that the 80MHz bandwidth meets the system frequency response needs without excessive gain peaking.

Part Context

This part belongs to the EL2228 family of dual low-noise amplifiers. It is functionally equivalent to the EL2228CY but utilizes an 8-lead Small Outline Integrated Circuit (SOIC) package instead of the Mini Small Outline Package (MSOP). Both variants share identical electrical performance specifications and pinout configurations.
