EL5263IS

Overview

The EL5263IS is a dual-channel, low-power current feedback amplifier manufactured by Renesas Electronics (formerly Elantec). It features a bandwidth of 420 MHz and a slew rate of 2.5 kV/us. The device operates on a supply voltage range of 5 V to 12 V with a quiescent current of 1.5 mA per channel. Key electrical specifications include an input offset voltage of 1.5 mV, a common-mode rejection ratio of 62 dB, and an output current capability of 100 mA. It is housed in an SOIC-8 package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-channel architecture providing two independent high-speed amplifiers within a single compact package.
• Current feedback topology designed for applications requiring fast transient response and wide bandwidth.
• Low power consumption profile suitable for battery-operated or thermally constrained systems.

Applications

• Video signal processing circuits
• High-speed data acquisition systems
• Test and measurement instrumentation

Procurement Notes

Verify the manufacturer status carefully as this component may be classified as obsolete or end-of-life depending on the specific production lot date. Confirm availability through authorized distributors only. Ensure the datasheet version matches the specific manufacturing batch requirements for your design. Check for RoHS compliance documentation if required by your regional regulations. Validate that the SOIC-8 footprint matches your PCB layout constraints.

Selection Notes

Select this component when a dual-channel solution is required for high-speed signal conditioning. The current feedback architecture offers superior slew rate performance compared to voltage feedback alternatives at similar bandwidths. Consider the 100 mA output drive capability for direct driving of transmission lines. Evaluate the 1.5 mA quiescent current against system power budgets. Ensure the 5 V to 12 V supply range aligns with the available power rails in the target application.

Part Context

This part belongs to the EL5263 series of low-power current feedback amplifiers. It represents a transition period product often associated with the Intersil brand before its acquisition by Renesas Electronics. The device is designed to replace older discrete solutions or single-channel amplifiers where space saving is critical. It shares functional similarities with other members of the family but differs in packaging and specific pinout configurations.

Replacement Considerations

Check for EL5263ISZ as a potential lead-free variant. Verify compatibility with EL5263IYZ for tape-and-reel packaging needs. Consult official substitution guides for any updated revisions.

FAQ

What is the difference between the EL5263IS and EL5263ISZ?

The EL5263ISZ is typically the lead-free, RoHS-compliant version of the EL5263IS, which may contain lead. Both share identical electrical characteristics and pinouts.

Is the EL5263IS a voltage feedback or current feedback amplifier?

It is a current feedback amplifier (CFA), which provides a constant bandwidth regardless of gain settings up to unity.
