EL5329IRZ

Overview

The EL5329IRZ is a high-speed, low-power voltage feedback operational amplifier manufactured by Elantec Semiconductor. It features a wide bandwidth and fast settling time suitable for demanding analog signal processing applications. The device operates within a supply voltage range of ±2.25V to ±18V and includes internal frequency compensation to ensure stability in various configurations. Packaged in a standard 14-pin plastic DIP or SOIC format, it integrates precision input stages designed for low noise and high common-mode rejection ratios.

Feature Summary

• High slew rate capability for rapid signal transitions
• Low power consumption profile optimized for battery-operated systems
• Internal frequency compensation eliminates external component requirements
• Wide single-supply or dual-supply operating voltage range

Applications

• Video buffering and line driving circuits
• Portable instrumentation requiring low power operation
• Active filtering in communication systems
• Precision data acquisition front-ends

Procurement Notes

Verify the specific suffix (e.g., IRZ) against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints, as pinouts may vary between DIP and surface-mount variants. Check for RoHS compliance status if required by project specifications. Confirm availability through authorized distributors as older components may have limited stock.

Selection Notes

Select this component when a balance between speed and power efficiency is critical. Compare slew rate and gain-bandwidth product against alternative op-amps to ensure sufficient margin for the target application frequency. Consider thermal dissipation requirements if operating near maximum supply voltages. Validate input offset voltage and bias current specifications against sensor interface needs.

Part Context

Elantec Semiconductor specialized in high-performance mixed-signal integrated circuits before being acquired by Intersil, which later became part of Renesas Electronics. The EL5329 belongs to a family of general-purpose operational amplifiers designed for industrial and consumer electronics. This lineage ensures that design documentation remains accessible through major semiconductor archives despite corporate restructuring.

Replacement Considerations

Direct replacements include the EL5329IUZ for surface-mount applications or equivalents from other manufacturers offering similar voltage feedback architectures. Verify pin compatibility and electrical parameters such as slew rate and supply current before substitution. Consult updated datasheets from current owners like Renesas for any revised mechanical drawings.
