ADAU1401YSTZ

Overview

The ADAU1401YSTZ is a SigmaDSP audio processor featuring a 28-/56-bit, 50 MIPS core. It integrates two stereo ADCs and four DACs with 24-bit resolution. The device provides 98.5 dB analog input-to-output dynamic range. Each ADC achieves an SNR of 100 dB and THD+N of −83 dB. Each DAC delivers an SNR of 104 dB and THD+N of −90 dB. It operates on 3.3 V analog/PLL supplies and 1.8 V digital supply. The component supports sampling rates up to 192 kHz and includes a self-boot mechanism from serial EEPROM.

Procurement Notes

Verify the specific package variant against the datasheet ordering guide. Confirm that the YSTZ suffix corresponds to the 48-lead plastic LQFP package. Ensure the revision level matches the required design specifications before procurement.

Selection Notes

Select this component when a complete single-chip audio solution is required. It combines high-performance conversion with programmable signal processing. Verify power supply requirements for AVDD at 3.3 V and DVDD at 1.8 V. Check interface compatibility for I2C or SPI control.

Part Context

This part belongs to the Analog Devices SigmaDSP family. It is designed as a standalone audio subsystem. The device replaces discrete DSP and converter combinations in compact designs.

Replacement Considerations

Consult the official datasheet ordering guide for verified alternative part numbers. Do not assume cross-compatibility with other series without electrical parameter verification.
