Frequently Asked Questions
What sample rate and bit depth does the ADAU1401YSTZ support for audio processing?
The ADAU1401YSTZ supports audio sample rates up to 96 kHz and uses a 28-/56-bit extended-precision DSP core, providing ample dynamic range and precision for high-fidelity audio filtering, equalization, and effects processing in consumer and professional designs.
Can the ADAU1401YSTZ operate without an external host microcontroller in a finished product?
Yes. The ADAU1401YSTZ includes on-chip program and data RAM as well as a self-boot mode that loads a stored program from an external serial EEPROM at power-up over I2C, allowing it to run standalone DSP algorithms in production systems without a dedicated host processor.
How many ADC and DAC channels does the ADAU1401YSTZ integrate, and what package does it come in?
The ADAU1401YSTZ integrates 2 stereo ADC inputs and 4 DAC output channels in a 48-pin LQFP (7 mm x 7 mm) surface-mount package, making it a compact, single-chip audio front-end and processing solution suitable for space-constrained PCB designs.
Which audio product categories are best served by the ADAU1401YSTZ compared to simpler codec ICs?
Unlike a basic stereo codec, the ADAU1401YSTZ includes a fully programmable SigmaDSP core running at 294.9 MHz, enabling parametric EQ, crossover filters, dynamic-range compression, and custom IIR/FIR algorithms—making it the preferred choice for active speakers, hearing instruments, and smart audio systems requiring on-device signal processing beyond simple A/D conversion.
