6PAIC3106IRGZRQ1

Overview

The TLV320AIC3106IRGZRQ1 is an automotive-grade, low-power stereo audio CODEC manufactured by Texas Instruments. It integrates two ADCs and two DACs with a 16-bit resolution, supporting digital interfaces including I2C, SPI, and I2S. The device operates within a supply voltage range of 1.1 V to 3.6 V and functions reliably across a temperature range of -40°C to +85°C. Key performance metrics include signal-to-noise ratios of 92 dB for the ADC and 102 dB for the DAC. It is housed in an NFBGA-80 package suitable for surface-mount installation.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliable operation in vehicle environments
• Integrated stereo audio processing with dual analog-to-digital and digital-to-analog converters
• Flexible digital connectivity supporting multiple industry-standard serial interface protocols

Applications

• In-car infotainment systems requiring high-fidelity audio reproduction
• Digital voice recognition modules for hands-free communication
• Active noise cancellation circuits in automotive headrests or cabin speakers

Procurement Notes

Verify that the component carries the specific 'RQ' suffix indicating automotive grade qualification. Confirm the package type matches the required PCB footprint and ensure compatibility with the target operating temperature range. Cross-reference the manufacturer's latest datasheet to validate pin assignments and electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this component when designing systems requiring certified automotive reliability alongside low power consumption. Ensure the host processor supports the necessary I2C or SPI control lines. Verify that the system power rails align with the 1.1 V to 3.6 V input range. Consider the NFBGA-80 package constraints during layout planning to maintain signal integrity for the stereo audio paths.

Part Context

This part belongs to the TLV320AIC3106 family of audio codecs. The 'RQ1' suffix specifically denotes its automotive qualification status under AEC-Q100 standards. It serves as a specialized variant designed for harsh environmental conditions found in vehicles, distinguishing it from standard commercial grade counterparts in the same series.

Replacement Considerations

Direct substitutes include other AEC-Q100 qualified stereo audio CODECs from Texas Instruments. Verify pin-to-pin compatibility if replacing existing designs. Check for equivalent SNR specifications and interface support to ensure seamless integration without hardware modifications.
