Audio Special Purpose Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm package type and reel specifications. Ensure the procurement channel provides valid traceability for AEC-Q100 certified components. Confirm that the delivered units match the 48-TQFP (7x7) physical dimensions and electrical parameters listed in the datasheet.

Audio Special Purpose Selection Notes

Select this component when a four-channel audio transceiver with differential outputs is required for automotive environments. The low voltage supply requirement of 1.65V to 1.95V must align with the system power design. Verify compatibility with I2C or SPI host controllers and ensure the operating temperature range meets the specific application's thermal constraints.

Audio Special Purpose Part Context

This part belongs to the DIX series of audio transceivers from Texas Instruments. It is distinct from other audio ICs due to its specific automotive qualification and four-channel capability. The TPFBRQ1 suffix indicates the tape and reel packaging and automotive grade status.

Audio Special Purpose Replacement Considerations

Check for direct pin-to-pin replacements within the DIX family or equivalent automotive-qualified audio transceivers. Verify that any substitute maintains the 1.65V-1.95V supply range and 48-TQFP footprint.
