Overview
The ADAU1860BCBZRL is a low-power audio codec featuring three analog-to-digital converters and one digital-to-analog converter, integrated with programmable FastDSP and Tensilica HiFi 3z audio processing engines. It supports sample rates up to 768 kHz with a maximum group delay of 5 μs at that rate. The device includes four asynchronous sample rate converters, eight interpolators, and eight decimators. Analog performance specifications include an SNR of 106 dB for differential line inputs and 110 dB for the DAC output. Power supplies operate within ranges of 1.7 V to 1.98 V for AVDD/HPVDD/IOVDD and 0.85 V to 1.21 V for DVDD.
Feature Summary
- Integrates dual DSP cores (FastDSP and Tensilica HiFi 3z) for flexible audio processing
- Supports multiple input types including differential/single-ended lines and digital microphones
- Features built-in asynchronous sample rate converters and digital filters
- Provides self-boot capability from external QSPI flash memory
Applications
- Noise canceling handsets, headsets, and headphones
- Bluetooth active noise canceling devices
- Smartphones and personal navigation devices
- Multimedia speaker systems
Procurement Notes
Verify component authenticity by checking markings against official datasheet pinouts and ordering information. Confirm package type matches the 56-ball WLCSP specification. Ensure environmental compliance documentation aligns with project requirements before finalizing procurement.
Selection Notes
Select this component when a compact solution combining high-performance audio conversion with embedded DSP capabilities is required. Consider the specific power supply voltage requirements for AVDD, DVDD, and IOVDD during system design. Evaluate the available serial port configurations and GPIO flexibility against interface constraints.
Part Context
This part belongs to the ADAU1860 family, which shares identical specifications and functionality with the ADAU1860-1. The distinction lies in regional availability; the ADAU1860 is designated for customers located in the People's Republic of China, while the ADAU1860-1 serves other regions.
Replacement Considerations
The ADAU1860-1 is the direct functional equivalent for non-PRC markets. No other cross-model replacements are documented in the provided source material.
