ADAU1777BCBZRL

Overview

The ADAU1777BCBZRL is a low-power audio codec with an integrated digital signal processing engine, packaged in a WFBGA-36 format. It features four single-ended analog inputs and two stereo analog outputs, supporting serial port sampling rates from 8 kHz to 192 kHz. The device provides 5 μs of analog-to-analog latency at high sample rates and includes full-duplex asynchronous sample rate converters. Analog performance specifications include a 102 dB SNR for the ADC path and 108 dB SNR for the DAC path. Power supplies operate within ranges of 1.71 V to 3.63 V for analog and I/O sections, and 1.045 V to 1.98 V for the digital core.

Feature Summary

• Integrated programmable audio processing engine featuring biquad filters, limiters, volume controls, and mixing capabilities.
• Ultra-low latency analog-to-analog conversion optimized for noise-canceling headset applications.
• Supports dual stereo digital microphone inputs alongside configurable analog line or microphone inputs.
• Includes built-in PLL clock generation and self-boot functionality from external I2C EEPROM.

Applications

• Noise canceling handsets, headsets, and headphones
• Bluetooth active noise canceling (ANC) devices
• Personal navigation devices
• Digital still and video cameras

Procurement Notes

Verify the specific suffix BCBZRL against the manufacturer's current ordering guide to confirm package type and reel specifications. Ensure that the required operating voltage levels match the system design constraints for AVDD, IOVDD, and DVDD before finalizing procurement.

Selection Notes

Select this component when ultra-low latency is critical for active noise cancellation loops. Evaluate power consumption requirements against the available management settings, as performance modes vary significantly between normal operation and extreme power saving configurations.

Part Context

This part belongs to the ADAU1777 series of mixed-signal audio processors. It combines high-fidelity data conversion with a flexible DSP core, allowing for complex audio signal processing directly within the codec without requiring a separate processor chip.
