ISL55291IUZ

Overview

The ISL55291IUZ is a dual, high-speed voltage feedback operational amplifier manufactured by Elantec. It features an 800 MHz bandwidth and rail-to-rail output capability, designed for demanding signal processing applications. The device operates within a supply voltage range of ±2.5V to ±15V and supports surface mount packaging in a 10-MSOP format. It maintains a slew rate of 1600 V/µs and low input bias current, ensuring precise amplification with minimal distortion across the specified temperature range.

Feature Summary

• Dual channel configuration providing two independent high-speed amplifiers in a single package
• Rail-to-rail output stage enabling maximum dynamic range utilization near supply rails
• High bandwidth and fast slew rate suitable for wideband signal conditioning

Applications

• Video signal processing and buffering
• High-speed data acquisition systems
• Instrumentation front-end amplification

Procurement Notes

Verify the specific suffix 'IUZ' corresponds to the RoHS-compliant, lead-free variant with tape-and-reel or tube packaging as defined in the official datasheet. Confirm the operating temperature range matches your environmental requirements. Ensure the pinout aligns with your PCB footprint design, as MSOP packages have specific thermal pad requirements. Cross-reference the manufacturer's latest documentation to confirm current production status and any potential obsolescence notices.

Selection Notes

Select this component when dual-channel performance is required alongside rail-to-rail output swing. Consider the 800 MHz bandwidth and 1600 V/µs slew rate for applications requiring fast transient response. Evaluate the 10-MSOP package size against available board space. Compare power consumption specifications against system constraints, noting the supply voltage range flexibility from ±2.5V to ±15V.

Part Context

Elantec Semiconductor, now part of Renesas Electronics, specializes in analog integrated circuits. The ISL55291 belongs to a family of high-speed operational amplifiers designed for video and communication infrastructure. This series emphasizes precision and speed, catering to industries requiring reliable signal integrity in compact form factors.

Replacement Considerations

Check for direct cross-reference part numbers from Elantec/Renesas catalogs. Verify that alternative devices match the 800 MHz bandwidth, rail-to-rail output, and 10-MSOP package dimensions. Ensure pin compatibility to avoid redesigning the printed circuit board layout.
