6PAIC3104IRHBRQ1

Overview

The 6PAIC3104IRHBRQ1 is an automotive-grade, low-power stereo audio codec designed for infotainment and instrument cluster applications. It integrates two analog-to-digital converters (ADCs) and two digital-to-analog converters (DACs) within a VQFN-32 package. The device supports serial interfaces including I2C for control. It operates with a supply voltage range of 1.1 V to 3.6 V and meets AEC-Q100 qualification standards. The operational temperature range spans from -40°C to +85°C. Key performance metrics include a signal-to-noise ratio of 92 dB for the ADC and 102 dB for the DAC, with total harmonic distortion plus noise specified at -89 dB for the ADC and -84 dB for the DAC.

Feature Summary

• Automotive-grade design qualified under AEC-Q100 standards for reliability in vehicle environments.
• Integrated stereo audio processing with dual ADC and DAC channels for complete audio signal conversion.
• Low-power architecture optimized for portable and battery-operated automotive systems.

Applications

• Automotive infotainment systems
• Instrument cluster audio interfaces

Procurement Notes

Verify the specific suffix Q1 confirms automotive qualification status against the official Texas Instruments datasheet. Ensure the VQFN-32 package dimensions match the target PCB footprint. Confirm that the I2C interface compatibility aligns with the host controller's protocol requirements before finalizing procurement.

Selection Notes

Select this component when an automotive-certified stereo codec is required for infotainment or cluster displays. Compare SNR and power consumption against non-automotive alternatives like the TLV320AIC3104 if cost is a primary driver but automotive reliability is not mandatory. Verify that the 3.6 V maximum supply voltage suits the system power rails.

Part Context

This part belongs to the TLV320AIC3104 family, specifically tailored for automotive use. It shares functional similarities with the standard TLV320AIC3104 but includes enhanced durability features and qualification testing required for automotive electronics. The '6P' prefix often denotes specific automotive or specialized variants within the manufacturer's portfolio.

Replacement Considerations

The TLV320AIC3104 serves as the commercial counterpart. For direct automotive replacements, verify availability of other AEC-Q100 qualified codecs in the same package. Cross-reference pinouts and register maps to ensure software compatibility during substitution.
