EL2280CS

Overview

The EL2280CS is a dual current-feedback operational amplifier manufactured by Intersil. It provides a -3dB bandwidth of 250MHz at a gain of +1 while consuming only 3mA of supply current per amplifier. The device supports 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 electrical parameters include a slew rate of 1200V/µs and differential gain/phase errors of 0.05%/0.05° into 150Ω.

Feature Summary

• Dual topology configuration for integrated signal processing
• High-speed current-mode feedback architecture
• Low power consumption with minimal supply current draw
• Wide single- and dual-supply voltage operation range

Applications

• HDSL amplifiers
• Video amplifiers
• Cable drivers
• RGB amplifiers

Procurement Notes

Verify the manufacturer source, as Intersil operations were acquired by Renesas Electronics. Confirm the specific suffix 'CS' matches the required package type and temperature grade in the official datasheet. Ensure compatibility with current design specifications before procurement.

Selection Notes

Select this component for applications requiring high bandwidth and low power consumption simultaneously. The dual configuration reduces board space compared to single amplifiers. Verify that the load impedance and supply voltage requirements align with the specified operating conditions for optimal performance.

Part Context
