Frequently Asked Questions
How many audio inputs and outputs does the ADAU1701 provide for a multi-channel design?
The ADAU1701 provides 2 ADC inputs and 4 DAC outputs, supporting stereo input and quad output configurations at sample rates up to 192 kHz, making it suitable for surround sound processing and active speaker crossover systems.
Can the ADAU1701 operate autonomously without a host microcontroller?
Yes, the ADAU1701 can self-boot from an external I2C EEPROM, storing up to 1024 DSP program instructions and coefficient data, enabling fully standalone operation in audio equipment without requiring a dedicated host processor at runtime.
What DSP word length does the ADAU1701 use for signal processing calculations?
The ADAU1701 uses a 28-bit data path with 56-bit accumulator, delivering high dynamic range processing at 48 kHz standard sample rates with up to 144 dB of dynamic range, reducing quantization noise in precision audio applications.
For a professional active loudspeaker design, how does ADAU1701 compare to a discrete DSP solution?
The ADAU1701 integrates 2 ADC inputs, 4 DAC outputs, and a 28/56-bit DSP core into a single chip, replacing dozens of discrete components and reducing BOM cost. A discrete solution would require separate ADC, DAC, and DSP ICs plus interface logic, significantly increasing board area and design complexity.
