EL2276CSZ-T7

Instrumentation, Op Amps, Buffer Amps Overview

The EL2276CSZ-T7 is a dual current-feedback operational amplifier manufactured by Renesas Electronics Corporation 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. The amplifier can deliver an output current of 55mA while swinging to ±4V on ±5V supplies.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the component matches the exact part number EL2276CSZ-T7, ensuring it includes the 'Z' suffix for lead-free (RoHS compliant) status and the '-T7' suffix indicating the 7-inch tape and reel packaging format. Confirm the manufacturer is Renesas Electronics Corporation or its predecessor Intersil. Check datasheet revision FN7054.1 for accurate electrical specifications before integration.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low power consumption combined with high bandwidth is required for video or HDSL applications. The current-feedback topology maintains relatively constant bandwidth regardless of closed-loop gain changes. Ensure the application supports the specified supply voltage range of ±1.5V to ±6V or +3V to +12V. Consider the disable pin logic levels if power management is critical.

Instrumentation, Op Amps, Buffer Amps Part Context

The EL2276 series consists of dual current-feedback operational amplifiers designed for low-power, high-bandwidth applications. The EL2276CSZ-T7 variant specifically denotes the lead-free, RoHS-compliant version packaged in a 14-pin Small Outline Integrated Circuit (SOIC) form factor. This family is suitable for portable computing and video processing where aggressive pricing and low cost are advantageous alongside performance metrics.
