6PAIC3254IRHBRQ1

Overview

The Texas Instruments 6PAIC3254IRHBRQ1 is an automotive-grade, ultra-low-power stereo audio codec featuring embedded miniDSP capabilities. It supports high-resolution audio processing with a 32-bit resolution and sampling rates up to 192 kHz. The device integrates two ADCs and two DACs, providing a dynamic range of 100 dB for the ADC and 93 dB for the DAC. Operating within a supply voltage range of 1.5 V to 1.95 V, it ensures efficient power management in mobile applications. The component utilizes I2C and SPI serial interfaces for control and data transmission.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliable operation in vehicle environments
• Integrated miniDSP engine enables flexible digital signal processing without external processors
• Ultra-low power architecture designed to extend battery life in portable and mobile devices
• High-fidelity audio performance with differential inputs and low total harmonic distortion

Applications

• Automotive infotainment systems requiring robust audio processing
• Mobile handsets and tablets needing compact, low-power audio solutions
• Portable media players demanding high dynamic range and clarity
• Voice recognition modules utilizing integrated DSP for noise reduction

Procurement Notes

Verify that the specific suffix IRHBRQ1 denotes the automotive grade variant, as standard commercial versions may lack required reliability certifications. Confirm package compatibility with VQFN-32 footprints during PCB layout. Ensure design reviews account for the specified operating temperature range of -40°C to +85°C. Cross-reference datasheet revisions to confirm interface timing requirements match system constraints.

Selection Notes

Select this component when automotive certification is mandatory alongside low-power stereo audio processing. The embedded miniDSP reduces system complexity by handling digital filtering and effects internally. Compare power consumption metrics against non-automotive alternatives if vehicle qualification is not required. Evaluate the 100 dB ADC dynamic range against application-specific signal-to-noise requirements.

Part Context

This part belongs to the TLV320AIC3254 family, specifically tailored for automotive applications. The '6P' prefix indicates the automotive-grade version, while 'Q1' signifies AEC-Q100 qualification. It shares architectural similarities with the commercial TLV320AIC3254 but includes enhanced testing and reliability features. The RHBR suffix identifies the VQFN-32 package with reel tape packaging format.

Replacement Considerations

The commercial equivalent is the TLV320AIC3254IRHB, though it lacks automotive qualification. For direct functional substitution in non-automotive contexts, verify pinout compatibility. No other TI part numbers are explicitly confirmed as drop-in replacements in public documentation.
