EL2170CS

Overview

The EL2170CS is a single current-feedback operational amplifier featuring a 70 MHz -3dB bandwidth at unity gain and a supply current of 1 mA per amplifier. It supports dual supplies from ±1.5V to ±6V or single supplies from +3V to +12V. The device delivers an output current of 100 mA with voltage swings to ±4V on ±5V supplies. Key electrical characteristics include an 800 V/µs slew rate and differential gain/phase errors of 0.15% and 0.15° into a 150Ω load.

Feature Summary

• Current-mode feedback architecture enabling high-speed performance with low power consumption
• High output drive capability delivering 100 mA while maintaining large voltage swings
• Operates on low-voltage single or dual power supplies down to ±1.5V
• Available in compact SOT-23-5 package for space-constrained designs

Applications

• Low power and battery-powered applications
• HDSL amplifiers
• Video amplifiers
• Cable drivers
• RGB amplifiers

Procurement Notes

Verify the manufacturer source, as Intersil (now Renesas) acquired Elantec Semiconductor. Confirm that the EL2170CS designation aligns with the specific datasheet revision FN7053 or equivalent documentation provided by the current rights holder. Ensure the component matches the required pinout and thermal specifications for the intended PCB layout before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring high bandwidth relative to quiescent current consumption. The EL2170CS is suitable for applications needing significant output current drive without excessive power dissipation. Consider the SOT-23-5 package if board space is limited compared to standard SO packages. Evaluate stability requirements carefully, as current-feedback amplifiers have different compensation characteristics than voltage-feedback types.

Part Context

The EL2170CS belongs to the EL2170 family of current-mode feedback amplifiers, which also includes dual (EL2270) and quad (EL2470) variants. This family was originally developed by Elantec Semiconductor and later maintained by Intersil Corporation following its acquisition. The series is designed to provide high-speed signal processing capabilities in low-power environments, bridging the gap between general-purpose op-amps and specialized high-speed drivers.
