ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix E2 against the manufacturer's current datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the ordering quantity aligns with the standard taping packaging quantity of 1000 units if bulk procurement is intended, as cut tape availability may vary.

ADCs/DACs - Special Purpose Selection Notes

Select this component when high-resolution audio conversion is required with flexible filter options. Compare against the BD34302EKV-E2 if higher sampling rates (up to 1536 kHz) or improved dynamic range (130 dB) are necessary. Confirm interface compatibility with the host processor for both PCM and DSD data streams.

ADCs/DACs - Special Purpose Part Context

The BD34352EKV-E2 belongs to ROHM's MUS-IC series, designed for high-quality audio applications. It serves as a successor or alternative to models like the BD34301EKV, offering a balance of numerical performance and sound quality customization through its digital filter settings.

ADCs/DACs - Special Purpose Replacement Considerations

The BD34352EKV is the base model for the E2 variant. For higher performance needs, the BD34302EKV offers 1536 kHz sampling and 130 dB SNR. Verify pin compatibility before substituting with other family members.
