ADCs/DACs - Special Purpose Procurement Notes

This component is officially listed as End-of-Life (EOL) by STMicroelectronics. Manufacturers indicate that production has ceased and the part will be discontinued. Availability is limited to existing stock from distributors; no new manufacturing orders can be placed. Verify current stock status carefully before design-in, as supply is finite and subject to depletion without replenishment.

ADCs/DACs - Special Purpose Selection Notes

Select this part only if legacy compatibility or specific high-voltage DAC characteristics are required for antenna tuning. Due to its EOL status, alternative solutions should be evaluated for long-term projects. Ensure the 16-pin Flip-Chip footprint fits the PCB layout constraints. Confirm that the 2.3V to 5V supply range aligns with system power requirements.

ADCs/DACs - Special Purpose Part Context

The STHVDAC-253MF3 belongs to the STHVDAC series, which focuses on specialized analog output solutions for RF and wireless subsystems. It serves as a dedicated controller for varactor diodes in antenna matching networks. The product line emphasizes compact packaging and precise digital control for mobile and IoT devices requiring efficient impedance matching.

ADCs/DACs - Special Purpose Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Given the End-of-Life status, direct replacements must be identified through independent cross-reference tools or by consulting STMicroelectronics engineering support for updated portfolio recommendations.
