Four ADC, Two DAC Low Power Codec

with Audio Processor

ADAU1772

Data Sheet

Low power (15 mW for typical noise cancelling solution)

I²C and SPI control interfaces, self-boot from I²C EEPROM

7 MP pins supporting dual stereo digital microphone inputs,

stereo PDM output, mute, DSP bypass, push-button

volume controls, and parameter bank switching

FEATURES

Programmable audio processing engine

192 kHz processing path

Biquad filters, limiters, volume controls, mixing

Low latency, 24-bit ADCs and DACs

102 dB SNR (signal through PGA and ADC

with A-weighted filter)

107 dB combined SNR (signal through DAC and headphone

with A-weighted filter)

Serial port sample rates from 8 kHz to 192 kHz

38 μs analog-to-analog latency

APPLICATIONS

Noise cancelling handsets, headsets, and headphones

Bluetooth ANC handsets, headsets, and headphones

Personal navigation devices

Digital still and video cameras

4 single-ended analog inputs—configurable as microphone

or line inputs

GENERAL DESCRIPTION

The ADAU1772 is a codec with four inputs and two outputs that

incorporates a digital processing engine to perform filtering,

level control, signal level monitoring, and mixing. The path

from the analog input to the DSP core to the analog output is

optimized for low latency and is ideal for noise cancelling headsets.

With the addition of just a few passive components, a crystal,

and an EEPROM for booting, the ADAU1772 provides a

complete headset solution.

Dual stereo digital microphone inputs

Stereo analog audio output—single-ended or differential,

configurable as either line output or headphone driver

PLL supporting any input clock rate from 8 MHz to 27 MHz

Full-duplex, asynchronous sample rate converters (ASRCs)

Power supplies

Analog and digital I/O of 1.8 V to 3.3 V

Digital signal processing (DSP) core of 1.1 V to 1.8 V
