ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'DBTR' corresponds to the TSSOP-30 package and reel packaging configuration. Confirm that the hardware-controlled variant meets system design requirements, as software-configurable alternatives exist within the same family. Ensure compatibility with the intended host controller's digital interface protocols before finalizing procurement.

ADCs/DACs - Special Purpose Selection Notes

Select this component when hardware-based control logic is preferred over software configuration for the ADC settings. The wide industrial temperature range makes it suitable for environments exceeding standard commercial limits. Compare channel count and control interfaces against other PCM186x series variants to ensure alignment with the specific multi-channel or single-channel architecture needs.

ADCs/DACs - Special Purpose Part Context

This part belongs to the PCM186x series of audio ADCs from Texas Instruments. While the PCM1865 offers four channels with software control, the PCM1861 provides two channels with hardware control. This distinction allows designers to choose between flexibility and simplified hardware interfacing based on system constraints.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1861EVM serves as an evaluation module for this device. For functional replacements, consider other PCM1861 variants if different packaging options are required, ensuring the control method remains compatible with the existing hardware design.
