EL2228CSZ

Overview

The EL2228CSZ is a dual voltage feedback operational amplifier manufactured by Renesas Electronics Corporation. It features a 40 MHz gain bandwidth product and a 65 V/µs slew rate, supporting high-speed signal processing. The device operates within a supply voltage range of 5 V to 24 V and delivers an output current of 180 mA per channel. Key electrical specifications include a maximum input offset voltage of 200 µV and an input bias current of 4.5 µA. Power consumption is rated at 5 mA for both channels combined. The component is housed in an 8-SOIC package with a width of 3.90 mm.

Feature Summary

• Dual-channel architecture providing two independent voltage feedback amplifiers in a single integrated circuit.
• High-speed performance characterized by a 40 MHz gain bandwidth product and 65 V/µs slew rate.
• Robust output drive capability delivering 180 mA per channel for demanding load applications.
• Low input offset voltage of 200 µV ensuring precision in signal conditioning tasks.

Applications

• High-speed data acquisition systems requiring fast signal settling times.

Procurement Notes

Verify the obsolete status of the EL2228CSZ before initiating procurement processes. Confirm availability through authorized distributors or secondary market suppliers. Ensure that any substitute components meet the original electrical specifications and pinout requirements. Check for RoHS compliance and moisture sensitivity levels relevant to your assembly process. Validate supplier authenticity to prevent counterfeit components.

Selection Notes

Select this component when dual-channel operation with high speed and moderate output current is required. The 8-SOIC package suits surface-mount designs with space constraints. Consider the 5 V to 24 V supply range compatibility with standard logic and analog power rails. Evaluate the 40 MHz bandwidth against system frequency requirements. Assess thermal management needs based on the 5 mA quiescent current draw.
