EL2470CN

Instrumentation, Op Amps, Buffer Amps Overview

The EL2470CN is a quad current-feedback operational amplifier from the Elantec EL2xxx series. It provides a -3dB bandwidth of 70MHz at unity gain while consuming only 1mA of supply current per amplifier. The device supports dual supplies from ±1.5V to ±6V or single supplies from +3V to +12V. It delivers an output drive current of 55mA with voltage swings to ±4V on ±5V supplies. Key electrical parameters include a slew rate of 800V/µs and differential gain/phase errors of 0.15%/0.15° into a 150Ω load.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer source, as Intersil acquired Elantec Semiconductor. Confirm the specific suffix 'CN' denotes the correct package type and temperature range. Check for RoHS compliance status and ensure the component matches the required quad configuration for your circuit design.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple low-power, high-bandwidth channels are required. It is suitable for designs needing 70MHz bandwidth with minimal quiescent current. Consider the EL2270 if only two channels are needed, or the EL2170 for higher single-channel current drive capabilities.

Instrumentation, Op Amps, Buffer Amps Part Context

The EL2470CN belongs to the EL2xxx family of current-feedback operational amplifiers. This family includes single (EL2170), dual (EL2270), and quad (EL2470) variants. These devices share similar electrical characteristics, differing primarily in the number of amplifiers per package and specific pinout configurations.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same family include the EL2270 for dual-channel needs or the EL2170 for single-channel applications. Verify pin compatibility and package dimensions before replacing.
