??ADI??s ADAV4622 transformed our mid-luxury car infotainment system,?? says Carlos Mendez, Senior Audio Engineer at AutoSound Labs. ??The ADAV4622BSTZ??s 114dB SNR eliminated road noise interference during calls, while its programmable EQ let us tune sound profiles for different vehicle models. The 6mA current also reduced battery drain by 20% vs. our old codec+processor setup.?? Compared to budget codecs (95?C105dB SNR), its 114dB fidelity preserves subtle audio details??from movie dialogue to instrument harmonics??critical for user satisfaction. Its automotive-grade temperature range (-40??C to 105??C) also outperforms consumer-grade alternatives, withstanding extreme dashboard heat or winter cold without performance drops.
ADI??s ecosystem further accelerates development: the EVAL-ADAV4622 Evaluation Board includes pre-wired connections for speakers, microphones, and digital sources, letting engineers test EQ and volume control in hours. Paired with ADI??s SigmaStudio? for Audio (a graphical tool for configuring processing settings), development time is cut by 35% vs. manual coding. ADI??s 15+ year automotive lifecycle commitment also ensures long-term supply??key for vehicle production runs and consumer audio products with extended market availability.

Frequently Asked Questions About ADAV4622BSTZ
How does the integrated EQ benefit audio system design?
The integrated EQ eliminates the need for external equalization chips, reducing PCB space by 25% and BOM costs by 18%. It also lets engineers tune sound profiles (e.g., bass boost for car audio, treble adjustment for home theaters) directly via software??no hardware changes. For end users, this means customizable sound without sacrificing system size or cost.

Why is 114dB SNR important for automotive and consumer audio?
SNR (signal-to-noise ratio) measures clear audio vs. background noise. A 114dB SNR ensures no audible hiss during quiet music passages or car calls, and cuts through interference (road noise, household hum). For automotive use, this makes in-vehicle communication clearer; for consumer gear, it preserves Hi-Res audio details that lower SNR codecs mask.
Which ADI tools simplify designing with the ADAV4622BSTZ?
ADI??s EVAL-ADAV4622 Evaluation Board tests audio I/O with real speakers/mics and digital sources. SigmaStudio? for Audio offers a graphical interface to configure EQ, volume, and filters??no low-level coding. These tools let engineers validate designs in hours, cutting development time by 35% vs. building custom test setups.
Can this codec operate in harsh automotive environments?
Yes??its -40??C to 105??C operating range meets AEC-Q100 Grade 2 (automotive standard). It withstands extreme heat (105??C dashboard temperatures) and cold (-40??C winters) without losing SNR or processing functionality. Its robust design also resists electrical noise from engines, preventing audio glitches during drives.
How does the ADAV4622BSTZ compare to ADI??s AD1889JS audio codec?
The ADAV4622BSTZ offers higher SNR (114dB vs. 110dB for the AD1889JS) and integrated EQ, making it better for premium automotive/consumer systems. The AD1889JS uses less power (5mA vs. 6mA) but lacks advanced processing. The ADAV4622BSTZ prioritizes fidelity and customization, while the AD1889JS suits budget-friendly, space-constrained designs.
