EL5166IW-T7A

Overview

The EL5166IW-T7A is a single-channel current feedback operational amplifier manufactured by Renesas Electronics (formerly Intersil). It features a 1.4 GHz bandwidth and a 6 kV/µs slew rate, designed for high-speed signal processing applications. The device operates within a supply voltage range of 5 V to 12 V, consuming 8.5 mA of quiescent current. Key electrical specifications include a 500 µV input offset voltage, 57 dB common-mode rejection ratio, and 1.7 nV/√Hz input voltage noise density. It delivers 160 mA output current per channel and functions reliably across an operating temperature range of -40°C to +85°C in a compact SOT-23-6 surface-mount package.

Feature Summary

• High-speed current feedback architecture providing wide bandwidth and fast transient response
• Integrated enable control functionality for power management and signal gating
• Low input offset voltage and low noise characteristics suitable for precision video applications
• Compact SOT-23-6 packaging optimized for space-constrained surface-mount designs

Applications

• Video buffering and line driving circuits
• High-speed data acquisition systems
• RF signal conditioning stages
• Test and measurement equipment front-ends

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Ensure proper ESD handling procedures are followed during storage and installation. Cross-reference datasheet revisions to confirm pinout and electrical parameter consistency with existing design specifications.

Selection Notes

Select this component when high slew rate and wide bandwidth are critical requirements for the application circuit. Consider the SOT-23-6 package size if board real estate is limited compared to larger SOIC options. Evaluate the enable pin requirement against system power management strategies. Compare performance metrics such as noise density and output drive capability against alternative current feedback amplifiers to ensure optimal circuit efficiency.

Part Context

This part belongs to the EL5166 series of high-speed operational amplifiers developed by Intersil, now part of Renesas Electronics. The series includes variants with different packaging options such as SOIC-8 and SOT-23-6. These amplifiers are engineered for video and RF applications requiring fast settling times and high gain-bandwidth products. The T7A suffix typically indicates tape-and-reel packaging for automated assembly processes.

Replacement Considerations

Check for EL5166ISZ-T13 or EL5166IWZ-T7A as potential package or variant alternatives within the same family. Verify functional compatibility regarding pinouts and electrical specifications before substitution.
