EL5131IW-T7

Overview

The EL5131IW-T7 is a high-speed voltage feedback operational amplifier from the Intersil EL5130/EL5131 series, manufactured by Renesas Electronics Corporation. It features a 300MHz -3dB bandwidth and a 1500MHz gain-bandwidth product. The device delivers an ultra-low input noise voltage of 1.8nV/√Hz at 10kHz and a typical slew rate of 350V/µs. It operates on single supplies from 5V to 12V or dual supplies from ±2.5V to ±6V with a low supply current of 4mA. The component provides 100mA drive performance and maintains stability at gains as low as 5. It is housed in a 5-lead SOT-23 package.

Feature Summary

• Ultra-low noise performance suitable for sensitive signal processing applications
• High-speed operation with 300MHz bandwidth and 350V/µs slew rate
• Low power consumption with 4mA supply current
• Capable of driving loads with 100mA output current capability

Applications

• Imaging systems
• Instrumentation circuits
• Communications devices

Procurement Notes

Verify that the ordering suffix 'T7' corresponds to the 7-inch tape and reel packaging configuration containing 3000 pieces per reel. Confirm the specific manufacturer designation, as the datasheet identifies Intersil Americas Inc. as the original designer while Renesas Electronics Corporation is listed as the current manufacturer. Ensure compliance with RoHS standards and check for any relevant product change notices regarding the SOT-23-5 package.

Selection Notes

Select this component when designing circuits requiring high bandwidth combined with minimal noise contribution. It is appropriate for applications needing stable operation at low closed-loop gains, specifically down to a gain of 5. Consider the 5-lead SOT-23 package for space-constrained designs where a small footprint is necessary. Verify that the required supply voltage range aligns with the specified single or dual supply capabilities.

Part Context

This part belongs to the EL5130/EL5131 family of ultra-low voltage noise amplifiers. While the EL5130 variant includes a fast disable control pin, the EL5131 omits this feature to accommodate the smaller 5-lead SOT-23 package. Both devices share identical electrical characteristics regarding speed, noise, and drive capability, differing primarily in physical pinout and package type.

Replacement Considerations

The EL5130ISW-T7 serves as a functional equivalent but utilizes an 8-lead SOIC package rather than the SOT-23 form factor. Direct pin-to-pin replacement is not possible due to the difference in lead count and package dimensions.
