EL2276CSZ

Instrumentation, Op Amps, Buffer Amps Overview

The EL2276CSZ is a dual current-feedback operational amplifier housed in a 14-pin SOIC package. 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 features a disable function that reduces current consumption to 0mA and places the output in a high-impedance state. Each amplifier can deliver an output drive current of 55mA.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Dual topology current-feedback architecture
• Integrated disable/power-down feature reducing current to 0mA
• High output drive capability of 55mA per amplifier
• RoHS compliant Pb-free construction

Instrumentation, Op Amps, Buffer Amps Applications

• RGB amplifiers

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix (e.g., CSZ vs CS-T7) against the manufacturer's official documentation to confirm the exact package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements if applicable to the design. Cross-reference the datasheet revision date to confirm parameter accuracy before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring high bandwidth combined with low quiescent current. The current-feedback topology maintains relatively constant bandwidth as closed-loop gain increases. Verify that the application load does not exceed the absolute maximum ratings for output current or power dissipation, particularly when driving low impedance loads.

Instrumentation, Op Amps, Buffer Amps Part Context

The EL2276 is part of a family of current-mode feedback amplifiers manufactured by Intersil, now Renesas Electronics Corporation. This specific variant is the dual-channel version, distinct from the single-channel EL2176 and quad-channel EL2470 models. The 'Z' suffix indicates a lead-free, RoHS-compliant manufacturing process compatible with standard surface-mount assembly techniques.

Instrumentation, Op Amps, Buffer Amps FAQ

How is the amplifier disabled?

The amplifier is disabled by pulling the ENABLE pin above 4.5V or leaving it floating. It is enabled by pulling the ENABLE pin to 2.0V or less.

What is the input voltage range relative to the supply?

The input voltage range extends to within 1V of either supply rail.
