EL1516IS

Overview

The EL1516IS is a dual ultra-low noise voltage feedback operational amplifier manufactured by Renesas Electronics Corporation. It features a typical supply current of 5.5mA per amplifier and operates within a supply voltage range of 5V to 12V. The device provides a -3dB bandwidth of 350MHz at a gain of -1 and 250MHz at a gain of +2, with a slew rate reaching 128 V/µs. Input characteristics include a voltage noise density of 1.24 nV/√Hz and a current noise density of 1.5 pA/√Hz. It is housed in an industry-standard 8-lead Small Outline Integrated Circuit (SOIC) package.

Feature Summary

• Ultra-low noise performance suitable for detecting very low amplitude signals
• High-speed operation with wide bandwidth and fast slew rate
• Gain-of-2 stability with moderate power consumption
• Wide single or dual supply voltage operation

Applications

• ADSL line receiving applications
• VDSL receivers
• Home PNA designs
• Ultrasound input amplifiers
• Wideband instrumentation

Procurement Notes

Verify the specific manufacturer source, as Intersil was acquired by Renesas. Confirm that the datasheet revision FN7328 Rev 2.00 applies to your production requirements. Check for any End-of-Life notices or recommended replacement parts from the manufacturer's technical support center before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring high signal fidelity with minimal added noise. Ensure the application benefits from its voltage feedback topology, which allows for capacitors in the feedback path unlike current feedback amplifiers. Verify that the required bandwidth and output drive capabilities align with the specified electrical parameters under your operating conditions.

Part Context

This part belongs to the EL1516 family of dual ultra-low noise amplifiers. While the standard EL1516 lacks power-down functionality, the EL1516A variant includes enable and disable pins to reduce supply current significantly. Both variants share similar electrical performance metrics but differ in pinout configuration and package options.

Replacement Considerations

The datasheet explicitly states that no recommended replacement is available for this product. Users are advised to contact the Technical Support Center for further assistance regarding obsolete status or alternative solutions.
