EL5105IWZ-T7A

Overview

The EL5105IWZ-T7A is a single-channel, high-speed voltage feedback operational amplifier manufactured by Renesas Electronics Corporation. It features a 700 MHz bandwidth and slew-enhanced performance for rapid signal response. The device operates within a supply voltage range of 2.5 V to 6 V (single) or ±1.25 V to ±3 V (dual), drawing 2 mA of quiescent current per channel. Key electrical specifications include a maximum input offset voltage of 10 mV, an input noise density of 10 nV/√Hz, and a power supply rejection ratio (PSRR) of 70 dB. It utilizes a 5-pin SOT-23 package.

Feature Summary

• Slew-enhanced architecture designed for high-speed video and RF signal processing applications
• Low power consumption with 2 mA quiescent current per channel
• High gain bandwidth product of 700 MHz for wideband signal integrity
• Compact 5-pin SOT-23 surface-mount packaging

Applications

• Video buffering and line driving in display systems
• RF signal conditioning and amplification
• High-speed data acquisition front-ends
• Test and measurement equipment signal chains

Procurement Notes

Verify the exact suffix 'T7A' against the manufacturer's latest datasheet to confirm tape-and-reel quantity and specific manufacturing lot codes. Ensure compatibility with RoHS directives if required by your region. Cross-reference the part number with authorized distributors to avoid counterfeit components, as this series has been subject to obsolescence notices in related variants.

Selection Notes

Select this component when a single-channel op amp with 700 MHz bandwidth is required in a minimal footprint. It is suitable for designs needing low quiescent current alongside high slew rates. Compare input offset voltage and noise specifications against system requirements. Consider the SOT-23-5 package constraints for PCB layout and thermal management compared to larger packages offering better heat dissipation.

Part Context

This part belongs to the EL51xx series of high-speed operational amplifiers from Renesas (formerly Intersil). The series is characterized by its focus on video and broadband applications, offering a balance between speed and power efficiency. The EL5105 specifically targets single-channel implementations where space is limited but high-frequency performance is critical.

Replacement Considerations

Check for EL5105IWZ-T7 without the 'A' suffix for potential pin-compatible alternatives. Verify if newer Renesas revisions have superseded this specific marking code. Consult official substitution guides for any updated versions with improved reliability or extended temperature ranges.
