EL2286CS-T7

Overview

The EL2286CS-T7 is a dual current-feedback operational amplifier manufactured by Intersil, now part of Renesas Electronics. It provides two independent amplifiers within a single package, each achieving a -3dB bandwidth of 250MHz at a gain of +1 while consuming only 3mA of supply current per channel. The device operates with dual supplies ranging from ±1.5V to ±6V or single supplies from +3V to +12V. It features a disable/power-down function that reduces current consumption to 0mA and places outputs in a high-impedance state. The amplifier delivers an output drive current of 55mA with voltage swings to ±4V on ±5V supplies.

Feature Summary

• Dual amplifier topology providing two independent channels in one package
• Fast disable and power-down feature reducing current consumption to zero
• High slew rate of 1200V/µs for rapid signal response
• Low differential gain and phase error of 0.05% and 0.05° respectively

Applications

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

Procurement Notes

Verify the manufacturer status as Intersil products are now managed under Renesas Electronics. Confirm the specific suffix T7 indicates tape and reel packaging if required for automated assembly. Check for End-of-Life notifications or product discontinuance notices, as older Intersil components may have limited availability or require alternative sourcing strategies.

Selection Notes

Select this component when dual-channel high-speed signal processing is required with low power constraints. The 250MHz bandwidth and 1200V/µs slew rate make it suitable for video and broadband applications. Consider the disable feature for power management in battery-operated systems. Ensure the operating supply voltage range matches the system design requirements of ±1.5V to ±6V.

Part Context

The EL2286 is part of the EL2x86 family of triple and dual current-feedback amplifiers. It shares architectural similarities with the EL2386 (triple) and EL2186 (single). This family is designed for low-power, high-bandwidth applications such as video distribution and data transmission. The CS package denotes a small outline integrated circuit format.
