ISL55190IBZ

Overview

The ISL55190IBZ is a single ultra-low noise, ultra-low distortion, low power operational amplifier manufactured by Intersil. It features an 800MHz bandwidth and operates with a supply current of 30mA per channel. The device utilizes an 8-SOIC package and supports rail-to-rail output swing. It is designed for applications requiring high precision and minimal signal degradation in low-power environments.

Feature Summary

• Ultra-low noise performance for high-fidelity signal processing
• Ultra-low distortion characteristics ensuring accurate waveform reproduction
• Low power consumption suitable for battery-operated systems
• Rail-to-rail output capability maximizing dynamic range

Applications

• Precision data acquisition systems
• Medical instrumentation requiring low noise amplification
• Audio processing circuits demanding high fidelity
• Test and measurement equipment front-ends

Procurement Notes

Verify the manufacturer source to ensure authenticity, as Intersil products are now part of Renesas Electronics. Confirm the specific suffix 'IBZ' indicates the standard SOIC-8 package variant. Check for RoHS compliance status if required by your manufacturing standards. Ensure the operating temperature range aligns with your system's environmental specifications before finalizing procurement.

Selection Notes

Select this component when both low noise and low power are critical constraints. Compare against other Intersil op-amps like the ISL55191 if dual-channel functionality is needed instead of single-channel. Consider the 800MHz bandwidth limit for high-speed applications. Evaluate the rail-to-rail output against requirements for input common-mode voltage ranges to ensure compatibility with the signal source.

Part Context

The ISL55190IBZ belongs to the Intersil family of precision operational amplifiers designed for high-performance analog signal conditioning. It complements other devices in the series such as the ISL55191, which offers similar electrical characteristics but in a dual-channel configuration. This component represents Intersil's focus on balancing speed, noise performance, and power efficiency in compact surface-mount packages.

Replacement Considerations

The ISL55191IBZ serves as a direct functional substitute if a dual-channel amplifier is acceptable or preferred over the single-channel ISL55190IBZ. Verify pinout compatibility and electrical parameter overlaps before substitution. No other direct single-channel replacements from the same manufacturer series are explicitly documented in the provided reference material.
