ADAU1860-1BCBZRL

Overview

The ADAU1860-1BCBZRL is a low-power audio codec featuring three analog-to-digital converters and one digital-to-analog converter. It integrates a Tensilica HiFi 3z DSP core and a programmable FastDSP engine for real-time audio processing. The device supports sample rates up to 768 kHz with a maximum group delay of 5 μs at high speeds. Key electrical parameters include a 24-bit resolution, 106 dB SNR for the ADC path, and 110 dB combined SNR for the DAC path. Power supplies operate between 1.7 V and 1.98 V for AVDD/HPVDD/IOVDD, and 0.85 V to 1.21 V for DVDD. It utilizes a 56-ball WLCSP package.

Feature Summary

• Integrates dual digital signal processors including a Tensilica HiFi 3z core and a programmable FastDSP engine for flexible audio manipulation.
• Supports multiple input configurations including three differential or single-ended analog inputs and eight digital microphone channels.
• Features asynchronous sample rate converters (ASRCs) and flexible serial audio ports supporting I2S, left justified, right justified, and TDM formats.
• Includes a built-in PLL supporting wide input clock ranges and self-boot capability from QSPI flash memory.

Applications

• Noise canceling handsets, headsets, and headphones
• Bluetooth active noise canceling (ANC) devices
• Smartphones and personal navigation devices
• Digital still and video cameras
• Multimedia speaker systems

Procurement Notes

Verify the specific suffix BCBZRL against the manufacturer's current ordering guide to ensure correct packaging and revision status. Confirm that the component designation matches the universal version intended for regions outside the People's Republic of China. Cross-reference the datasheet revision history to validate compatibility with existing design documentation.

Selection Notes

Select this component when a compact solution requiring integrated DSP capabilities and low latency is necessary. Ensure the system design accommodates the required power supply rails and thermal dissipation for the WLCSP package. Verify that the available serial interfaces and GPIO pins meet the specific connectivity requirements of the host processor.

Part Context

The ADAU1860-1 serves as the universal variant of the ADAU1860 family, designed for global distribution outside the People's Republic of China. Both variants share identical technical specifications, functional block diagrams, and performance characteristics. The distinction lies solely in regional availability and ordering restrictions defined by Analog Devices.

Replacement Considerations

The standard ADAU1860BCBZRL is functionally equivalent but restricted to customers within the People's Republic of China. No other direct pin-compatible substitutes are documented in the provided datasheet. Designers must verify regional ordering eligibility before substituting part numbers.
