EL5251IY

Overview

The EL5251IY is a dual-channel, high-speed voltage feedback operational amplifier manufactured by Intersil. It features a 200MHz -3dB bandwidth and a slew rate of 67V/µs, providing DC accuracy with a 1mV offset and 10kV/V open-loop gain. The device operates on single supplies from 5V to 12V or dual supplies from ±2.5V to ±5V, consuming only 1.4mA per amplifier. Packaged in an industry-standard 8-lead SOIC, it supports the industrial temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture offering two independent amplifiers in a compact package
• High-speed performance with 200MHz bandwidth for video and communication applications
• Low power consumption suitable for battery-powered and portable equipment
• Industrial temperature operation ensuring reliability across wide environmental ranges

Applications

• High-speed video and monitor circuits
• Precision measurement instrumentation
• Communications devices requiring fast signal processing
• Handheld and portable electronic equipment

Procurement Notes

Verify the specific suffix 'IY' against official Intersil documentation to confirm the package type and temperature grade. Ensure compatibility with existing board layouts designed for 8-lead SOIC footprints. Confirm supply status as legacy components may have limited availability or require last-time-buy notifications from authorized distributors.

Selection Notes

Select this component when dual-channel high-speed amplification is required within space-constrained designs. Compare against single-channel alternatives if only one amplifier is needed to reduce cost. Verify that the 1.4mA quiescent current meets system power budgets. Ensure the 10kV/V open-loop gain is sufficient for the required linearity in the target application.

Part Context

This part belongs to the EL515x series of 200MHz voltage mode feedback amplifiers. It shares core electrical characteristics with the single-channel EL5151 and quad-channel EL5451 variants. The series is designed for applications demanding high speed and low power, bridging the gap between general-purpose op-amps and specialized video amplifiers.

Replacement Considerations

Check for direct pin-compatible replacements such as the EL5251 in different packaging options. Verify functional equivalents from other manufacturers offering similar 200MHz bandwidth and low supply current specifications. Ensure any substitute maintains the same 8-lead SOIC footprint and industrial temperature rating.
