EL1516ISZ

Overview

The EL1516ISZ is a dual ultra-low noise voltage feedback operational amplifier manufactured by Renesas Electronics, formerly Intersil. It features a high slew rate of 128 V/us and an input voltage noise density of 1.24 nV/sqrt Hz. The device operates on supply voltages ranging from 2.5 V to 6 V per rail or 5 V to 12 V total. Key electrical parameters include an input offset voltage of 3 mV, input bias current of 9 uA, and quiescent current of 14 mA. It is housed in an SOIC-8 surface-mount package and functions within a temperature range of -40 C to +85 C.

Feature Summary

• Dual channel architecture providing two independent low-noise amplifiers in a single package
• Ultra-low input voltage noise density suitable for precision signal conditioning
• High slew rate capability for fast transient response applications

Applications

• Precision sensor signal amplification
• Low-noise audio preamplifier stages
• Medical instrumentation front-ends

Procurement Notes

Verify the manufacturer origin as Renesas Electronics or Intersil when sourcing this component. Confirm the specific suffix 'T13' if reel packaging is required, as standard tape-and-reel options may vary. Ensure the SOIC-8 package matches your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component for designs requiring minimal input voltage noise and high speed. The dual configuration reduces board space compared to single-channel alternatives. Verify that the 14 mA quiescent current aligns with system power budgets. Ensure the operating voltage stays within the specified 2.5 V to 6 V per rail limits for optimal performance.

Part Context

This part belongs to the EL1516 series of ultra-low noise operational amplifiers. It represents a dual-channel variant designed for applications demanding high fidelity and low distortion. The component bridges the gap between general-purpose op-amps and specialized low-noise devices, offering balanced performance metrics.

Replacement Considerations

Check for direct pin-compatible replacements within the Renesas/Intersil portfolio. Verify that any substitute maintains the 1.24 nV/sqrt Hz noise density and 128 V/us slew rate specifications.
