• Configurable via standard I2C digital control interface
• Operates on low single-supply voltage ranging from 2.25V to 3.6V

Video Processing Applications

• Video display systems
• LCD panel driver circuits
• Video signal conditioning modules

Video Processing Procurement Notes

Verify the exact suffix against manufacturer documentation, as the provided model includes a -T7A tape-and-reel indicator not present in the primary datasheet listing which specifies tray packaging. Confirm current availability status, as the base ISL24858 series has been marked as obsolete or end-of-life in recent distributor records. Ensure the selected variant matches the required packaging format for automated assembly processes.

Video Processing Selection Notes

Select this component when designing video display interfaces requiring precise analog voltage references controlled digitally. The I2C interface allows for dynamic adjustment of output levels without external resistor networks. Consider the 28-QFN footprint for board space constraints. Verify that the operating supply voltage aligns with the system's 3.3V or 3.0V rails, staying within the specified 2.25V to 3.6V window.

Video Processing Part Context

The ISL24858 belongs to Renesas' portfolio of video processing support ICs, previously under the Intersil brand before acquisition. These devices address the need for accurate biasing in high-fidelity video paths. The family typically includes variants with different packaging options, such as QFN and TQFP, catering to various manufacturing requirements. The IRXZ suffix denotes the specific lead-free and RoHS-compliant version of the 28-QFN package.

Video Processing Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. The base ISL24858 series is listed as obsolete; consult Renesas official channels for direct replacement recommendations or last-time-buy information.
