Compared to converters with lower dynamic range, its 120dB performance ensures superior clarity, capturing both subtle ambient sounds and loud transients without distortion. This consistency is critical for immersive audio formats like 7.1 surround sound, where even minor channel differences break the illusion of spatial audio.
Unlike many alternatives limited to 96kHz, its 8kHz to 192kHz sample rate range supports both consumer and professional standards, from home theater (48kHz) to studio mastering (192kHz). The <2ms latency also outperforms competitors, ensuring lip-sync accuracy in video-audio systems??essential for live events and television production.

Veelgestelde vragen (FAQ)
How does the SRC4382IPFB synchronize 8 independent audio sources?
Its integrated sample rate converters align each channel to a common clock, eliminating timing mismatches that cause phase issues or echo. This is vital in setups with microphones, instruments, and preamps, ensuring all signals blend seamlessly into a cohesive audio experience.
Why is 120dB dynamic range important for multi-channel systems?
Dynamic range measures the ability to capture both quiet and loud sounds. 120dB ensures subtle details (e.g., a whisper in a podcast) and loud transients (e.g., a drum hit) are preserved across all 8 channels, maintaining consistent quality without channel-to-channel variation that degrades immersion.
Can the SRC4382IPFB work with legacy audio equipment?
Yes, it supports industry-standard interfaces (I2S, TDM) and I2C control, ensuring compatibility with both modern and older gear. This flexibility simplifies upgrades to existing systems, allowing gradual migration without replacing all components at once??reducing costs and downtime.
What benefits does 192kHz sample rate support offer?
192kHz support enables high-resolution audio processing, capturing finer frequency details than lower rates. This is critical for studio mastering, where preserving every nuance of a performance ensures the final product meets professional standards, and for future-proofing systems for emerging high-res formats.
How does the 48-TQFP package improve system design?
The 48-TQFP package balances pin count and thermal performance, allowing efficient heat dissipation in enclosed equipment like rack-mounted mixers. Its size simplifies PCB routing compared to larger packages, reducing design complexity while accommodating the 8-channel functionality needed for complex systems.
