Analog To Digital Converters (ADC) Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer, with discontinuance notifications dated June 25, 2021. Availability is restricted to remaining stock or third-party distributors. Verification of authenticity and lot traceability is critical due to the discontinued status. Buyers should confirm the specific tape-and-reel packaging quantity and ensure compliance with RoHS3 standards before procurement.

Analog To Digital Converters (ADC) Selection Notes

Designers should consider the 16-TSSOP package constraints and the 2.7V to 5.25V supply requirements when selecting this part. The 8-channel multiplexer configuration distinguishes it from lower-channel variants like the ISL26325. Ensure that the system's SPI timing aligns with the device's specifications. Given the EOL status, alternative sourcing strategies or redesign efforts may be necessary for long-term production viability.

Analog To Digital Converters (ADC) Part Context

The ISL26329 belongs to the ISL2632x family of low-power, 12-bit SAR ADCs from Renesas/Intersil. This family shares common architectural features but varies in channel count and packaging options. The 'T7A' suffix indicates a specific tape-and-reel packaging variant intended for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

Public documentation confirms the ISL26329FVZ (tube packaging) as a functional equivalent with identical electrical characteristics. No other direct cross-model substitutes are verified in the provided source material.
