EL2480CSZ-T13

Overview

The EL2480CSZ-T13 is a quad current-feedback operational amplifier manufactured by Renesas Electronics Corporation. It achieves a -3dB bandwidth of 250MHz at a gain of +1 while consuming only 3mA of supply current per amplifier. The device operates with dual supplies ranging from ±1.5V to ±6V, or single supplies from +3V to +12V. It can output 55mA while swinging to ±4V on ±5V supplies. Key specifications include a slew rate of 1200V/µs, an input offset voltage of 2.5mV typical, and a common-mode rejection ratio of 50dB. The component is housed in a 14-SOIC package.

Feature Summary

• Quad topology providing four independent amplifiers within a single package
• Current-feedback architecture maintaining consistent bandwidth across varying closed-loop gains
• Low power consumption with 3mA supply current per amplifier
• High output drive capability delivering up to 55mA

Applications

• HDSL amplifiers
• Video amplifiers
• Cable drivers
• RGB amplifiers
• Test equipment amplifiers

Procurement Notes

Verify the specific ordering suffix for tape and reel dimensions, as the EL2480CSZ-T13 indicates a 13-inch reel configuration. Confirm RoHS compliance status, noting that Intersil Pb-free products utilize special material sets compatible with both SnPb and Pb-free soldering operations. Ensure the datasheet version matches the design requirements, as specifications may vary between revisions.

Selection Notes

Select this component for applications requiring high bandwidth combined with low power dissipation. The current-feedback topology ensures stable performance regardless of closed-loop gain adjustments. Consider the 14-SOIC package constraints and thermal resistance when designing for high ambient temperatures or dense PCB layouts. Verify supply voltage ranges align with system requirements, specifically the ±1.5V to ±6V dual supply or +3V to +12V single supply limits.

Part Context

The EL2480 series belongs to Renesas' portfolio of high-speed analog signal processing components. Originally developed by Intersil, these amplifiers are designed for video and telecommunications markets. The CSZ-T13 variant represents the lead-free, tape-and-reel version of the standard SOIC packaged device, facilitating automated assembly processes.
