ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'KEG4' against official Texas Instruments documentation to confirm pinout compatibility and RoHS status. Ensure the source document explicitly lists this exact part number, as generic PCM1748 listings may refer to different packages or revisions. Cross-reference the manufacturer's current product status to determine availability.

ADCs/DACs - Special Purpose Selection Notes

Select the PCM1748KEG4 when a 24-bit stereo DAC with 100 dB SNR is required in a compact 16-pin SSOP form factor. Confirm that the system design accommodates the 4.5 V to 5.5 V single-supply requirement and the -25°C to +85°C operating temperature range. Verify interface compatibility with the target microcontroller or DSP.

ADCs/DACs - Special Purpose Part Context

This component belongs to the PCM1748 series of audio DACs from Texas Instruments. The series is designed for high-performance audio applications. The 'KEG4' designation indicates the specific package type (SSOP-16), temperature grade, and compliance with lead-free standards, distinguishing it from other variants like the PCM1748E.

ADCs/DACs - Special Purpose Replacement Considerations

Direct replacements must match the 24-bit resolution, 100 dB SNR, and 16-pin SSOP package. Verify electrical parameters such as supply voltage and interface type. Consult the manufacturer's obsolescence notices and recommended replacement guides for any discontinued variants.
