EL2270CS-T13

Overview

The EL2270CS-T13 is a dual current-feedback operational amplifier from the EL2170/EL2270/EL2470 family, manufactured by Intersil (Renesas). It achieves a -3dB bandwidth of 70MHz at a gain of +1 while consuming only 1mA 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 electrical parameters include an 800V/µs slew rate and differential gain/phase errors of 0.15%/0.15° into 150Ω. It is housed in an industry-standard SO-8 package.

Feature Summary

• Dual topology current-feedback architecture providing high-speed performance with low power consumption.
• Capable of delivering 55mA output current with significant voltage swing on standard ±5V supplies.
• Supports both single-supply and dual-supply operation down to ±1.5V for flexible system integration.

Applications

• Low power cable drivers
• HDSL amplifiers
• RGB video amplifiers

Procurement Notes

Verify the manufacturer source, as Intersil operations were acquired by Renesas Electronics. Confirm the specific suffix 'T13' indicates tape-and-reel packaging if required for automated assembly. Check RoHS compliance status against the latest datasheet revision, as older Intersil parts may have varying environmental certifications. Ensure the SO-8 package variant matches your PCB footprint requirements.

Selection Notes

Select this component when a balance between high bandwidth and low quiescent current is critical. The current-feedback architecture offers superior slew rate compared to voltage-feedback counterparts at similar power levels. Consider the EL2170 for single-channel needs or EL2470 for quad configurations within the same family. Verify that the 70MHz bandwidth meets the signal frequency requirements without excessive overshoot.

Part Context

The EL2270 belongs to the EL2170 series of current-mode feedback amplifiers designed for efficiency. This family includes single (EL2170), dual (EL2270), and quad (EL2470) variants. These devices are engineered for applications requiring fast transient response and minimal power draw, distinguishing them from higher-power but slower general-purpose op-amps.

Replacement Considerations

Public confirmed substitute part numbers: EL2170 (single channel version), EL2470 (quad channel version).
