EL1516ISZ

Overview

The EL1516ISZ 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. The component is housed in an industry-standard 8-lead 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
• Capable of driving low impedance loads effectively
• Stable at gains greater than or equal to two

Applications

• ADSL receivers
• VDSL receivers
• Home PNA receivers
• Ultrasound input amplifiers
• Wideband instrumentation

Procurement Notes

Verify the specific manufacturer origin as the product history involves Intersil and Renesas transitions. Confirm RoHS compliance status and lead-free material specifications against the latest datasheet revision. Ensure the ordering suffix matches the required package type and tape-and-reel quantity. Check for any engineering change notices that may affect pinout or electrical parameters before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring minimal signal degradation from internal noise sources. The dual configuration allows for differential signal processing within a compact footprint. Consider the thermal resistance and power dissipation limits when operating at maximum supply voltages or driving heavy loads. Verify that the required bandwidth aligns with the specified gain settings to ensure stability.

Part Context

This part belongs to the EL1516 family of dual ultra-low noise amplifiers designed primarily for line receiving applications in broadband communication systems. The ISZ designation indicates the standard plastic 8-lead Small Outline Integrated Circuit package variant. This series serves as a replacement for older components like the EL2227 in high-performance analog front-end designs.

Replacement Considerations

The datasheet explicitly states that no recommended replacement exists for this discontinued product. Designers must evaluate alternative dual ultra-low noise amplifiers with compatible pinouts and electrical specifications if redesigning the hardware.
