EL1516AIYZ

Overview

The EL1516AIYZ is a dual ultra-low noise voltage feedback operational amplifier manufactured by Renesas Electronics. It features a typical supply current of 5.7mA per amplifier and operates within a supply voltage range of 2V to 12V. The device provides a typical slew rate of 80V/µs and an input offset voltage of 3mV. Key electrical specifications include a voltage noise density of 1.24nV/√Hz and a current noise density of 1.5pA/√Hz at 100kHz. It incorporates enable and disable functions to reduce power consumption, with the package configuration being a 10-lead MSOP.

Feature Summary

• Incorporates dedicated enable and disable control pins to significantly reduce supply current during inactive states.
• Designed for high-speed signal processing with a gain-bandwidth product of 300MHz and stability at gains greater than two.
• Optimized for low-noise performance suitable for detecting very low amplitude signals in communication systems.

Applications

• ADSL receiver line interfaces
• VDSL receiver circuits
• Home PNA receivers
• Ultrasound input amplifiers
• Wideband instrumentation

Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to limited availability or obsolescence status. Confirm that the specific ordering suffix matches the required package type and lead finish specifications. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring minimal noise contribution from the amplifier stage itself. Consider the 10-lead MSOP package constraints regarding thermal dissipation and physical space. Evaluate the enable pin logic levels against the system's available control voltages to ensure proper power-down functionality.

Part Context

This device belongs to the EL1516 family of dual ultra-low noise amplifiers originally developed by Intersil Corporation. Following corporate mergers, manufacturing and support responsibilities transitioned to Renesas Electronics. The EL1516A variant specifically adds hardware control capabilities not present in the standard EL1516 model.

Replacement Considerations

The datasheet explicitly identifies the EL2227 as an upgrade replacement. No other substitute part numbers are documented in the provided source material.

FAQ

How does the EL1516AIYZ achieve lower power consumption?

It utilizes dedicated EN (Enable) pins. Applying a low logic level or allowing these pins to float enables the amplifiers, while applying a high logic level disables them, reducing supply current to approximately 5nA per amplifier.

What is the maximum operating temperature for this component?

The device is specified for operation over a temperature range of -40°C to +85°C.
