EL5171ISZ

Overview

The EL5171ISZ is a high-speed differential amplifier manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 4.75 V to 11 V and consumes 7.5 mA of supply current. The device features an input offset voltage of 1.5 mV and an input bias current of 6 µA. Electrical performance includes a slew rate of 800 V/µs, a gain-bandwidth product of 100 MHz, and a -3 dB bandwidth of 250 MHz. It provides a maximum output current of 120 mA per channel. The component is housed in an 8-SOIC package with a width of 3.90 mm and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides differential output for twisted-pair transmission applications
• Features external feedback configuration for flexible gain setting
• Delivers high-speed signal processing with 250 MHz bandwidth

Applications

• Differential twisted-pair drivers
• High-speed data communication interfaces
• Video signal distribution systems

Procurement Notes

Verify the specific suffix (e.g., ISZ vs ISZ-T7A) against official Renesas documentation to confirm pinout and packaging details. Confirm RoHS compliance status as manufacturing sites may vary. Check for obsolescence notices, as this component family has faced discontinuation alerts. Ensure moisture sensitivity level handling protocols are followed during assembly.

Selection Notes

Select this component when differential signaling with high bandwidth is required. Verify that the 11 V maximum supply voltage aligns with system power rails. Consider the 8-SOIC footprint constraints for PCB layout. Evaluate thermal dissipation requirements given the 7.5 mA quiescent current. Ensure external feedback components match the desired gain specifications.

Part Context

The EL5171 belongs to the EL5171/EL5371 series of differential line drivers designed for high-frequency applications. It is part of Renesas' portfolio of interface ICs, originally developed under the Intersil brand. The device complements other differential amplifiers in the lineup by offering specific external feedback capabilities distinct from internally compensated variants.

Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Generic differential amplifiers may not match the 250 MHz bandwidth or 800 V/µs slew rate. Verify pin compatibility if replacing with similar SOIC-8 packages.
