DIX4192IPFBRQ1

Audio Special Purpose Overview

The DIX4192IPFBRQ1 is a four-channel digital audio transceiver manufactured by Texas Instruments, designed for automotive applications. It operates within a supply voltage range of 1.65V to 1.95V and supports I2C and SPI interfaces for configuration. The device features differential outputs and is housed in a 48-TQFP package measuring 7x7 mm. It functions as an audio transceiver with a qualified AEC-Q100 grade, ensuring reliability under operating temperatures from -40°C to +85°C.

Audio Special Purpose Feature Summary

• Four-channel digital audio transceiver architecture
• AEC-Q100 qualified for automotive reliability
• Differential output capability
• I2C and SPI control interfaces

Audio Special Purpose Applications

• Automotive audio systems
• Digital audio interface circuits
• Vehicle infotainment networks

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix matches the required tape and reel packaging format. Confirm that the 1.65V to 1.95V supply voltage range aligns with the target system power rails. Ensure the design accommodates the 48-TQFP footprint dimensions of 7x7 mm during PCB layout.

Audio Special Purpose Selection Notes

Select this component when a four-channel transceiver with differential outputs is required for automotive environments. The narrow 1.65V-1.95V supply range necessitates careful power management design. Verify compatibility with existing I2C or SPI bus architectures for device configuration and status monitoring.

Audio Special Purpose Part Context

This part belongs to the DIX series of audio transceivers from Texas Instruments. It shares functional similarities with other automotive-grade audio interface components but is distinct in its four-channel configuration and specific low-voltage operation requirements compared to standard consumer audio ICs.

Audio Special Purpose Replacement Considerations

Check for direct pin-to-pin compatible alternatives within the DIX family. Verify if other AEC-Q100 qualified transceivers meet the 4-channel and differential output specifications without requiring schematic changes.
