EL5131IW-T7A

Overview

The EL5131IW-T7A is a high-speed voltage feedback amplifier from the EL5130/EL5131 series, manufactured by Renesas Electronics Corporation. It features a 300MHz -3dB bandwidth and an ultra-low input noise voltage of 1.8nV/√Hz at 10kHz. The device operates on single supplies from 5V to 12V or dual supplies from ±2.5V to ±6V, with a typical supply current of 4mA. It provides a slew rate of 350V/µs and maintains stability at gains as low as 5. The component is housed in a 5-lead SOT-23 package and is specified for operation over an ambient temperature range of -40°C to +85°C.

Feature Summary

• High-speed operation with 300MHz bandwidth and 350V/µs slew rate
• Stable operation at low closed-loop gains down to 5
• Capable of delivering 100mA continuous output drive current

Applications

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

Procurement Notes

Verify that the ordering suffix matches the specific tape and reel quantity requirements. Confirm the manufacturer designation aligns with Renesas Electronics Corporation specifications. Ensure the package type corresponds to the required 5-lead SOT-23 form factor. Validate RoHS compliance status if lead-free soldering processes are mandated for the assembly line.

Selection Notes

Select this amplifier when low noise and high speed are critical constraints. It is appropriate for applications demanding stable gain settings without oscillation risks at lower gains. Consider the power supply flexibility for both single and dual rail configurations. Evaluate the thermal dissipation capabilities within the small SOT-23 footprint against the expected operating ambient temperatures.

Part Context

This component belongs to the EL5130/EL5131 family of ultra-low noise, high-speed voltage feedback amplifiers. Originally developed by Intersil Corporation, the product line has been integrated into the Renesas Electronics portfolio. The series is designed to provide exceptional noise performance while maintaining extremely low power consumption, making it suitable for battery-operated or thermally constrained environments.

Replacement Considerations

The EL5131IWZ-T7A serves as the lead-free compliant alternative within the same package and specification set. Verify pinout compatibility before substitution. Check datasheet revisions to ensure electrical parameters remain consistent across manufacturing updates.
