EL5130IS-T7

Overview

The EL5130IS-T7 is a high-speed voltage feedback operational amplifier manufactured by Intersil, now part of Renesas Electronics. It features a 300MHz -3dB bandwidth and a 1500MHz gain-bandwidth product. The device operates on single supplies from 5V to 12V or dual supplies from ±2.5V to ±6V. Key electrical specifications include an ultra-low input noise voltage of 1.8nV/√Hz at 10kHz, a slew rate of 350V/µs, and a supply current of 4mA. It provides 100mA drive performance and maintains stability at gains as low as 5. The component is housed in an 8-lead SOIC package and is specified for operation over the -40°C to +85°C temperature range.

Feature Summary

• Ultra-low noise performance with 1.8nV/√Hz input voltage noise density
• High-speed voltage feedback architecture with 300MHz bandwidth
• Fast transient response characterized by a 350V/µs slew rate
• Integrated fast disable control pin for power management

Applications

• Imaging systems requiring low noise amplification
• Precision instrumentation circuits
• Communications devices and signal processing

Procurement Notes

Verify that the ordering suffix T7 corresponds to the 7-inch tape and reel packaging format. Confirm the specific manufacturer lineage, as Intersil products are now managed under Renesas Electronics. Ensure the procurement documentation references the FN7381.4 datasheet for accurate electrical parameters and handling procedures. Check for RoHS compliance status regarding the Pb-free plus anneal material sets.

Selection Notes

Select this amplifier for applications demanding high bandwidth combined with minimal noise contribution. It is suitable for designs requiring stable operation at low closed-loop gains. Consider the 8-lead SOIC package dimensions for PCB layout constraints. Evaluate the supply voltage requirements against the ±2.5V to ±6V dual supply or 5V to 12V single supply operating ranges.

Part Context

The EL5130 series belongs to a family of ultra-low voltage noise amplifiers designed for communications and imaging. The EL5130 variant includes a dedicated enable/disable pin, distinguishing it from the EL5131 which lacks this feature. Both share identical electrical characteristics but differ in pinout configuration. The IS suffix indicates the industrial temperature grade and SOIC package style.

Replacement Considerations

EL5130IS: Identical electrical specifications and functionality; differs only in bulk tube packaging rather than tape and reel.
