GENERAL DESCRIPTION

The ADAU1761 is a low power, stereo audio codec with

integrated digital audio processing that supports stereo 48 kHz

record and playback at 14 mW from a 1.8 V analog supply. The

stereo audio ADCs and DACs support sample rates from 8 kHz

to 96 kHz as well as a digital volume control.

The SigmaDSP® core features 28-bit processing (56-bit double

precision). The processor allows system designers to compensate

for the real-world limitations of microphones, speakers, amplifiers,

and listening environments, resulting in a dramatic improvement

in the perceived audio quality through equalization, multiband

compression, limiting, and third-party branded algorithms.

The SigmaStudio™ graphical development tool is used to program

the ADAU1761. This software includes audio processing blocks

such as filters, dynamics processors, mixers, and low level DSP

functions for fast development of custom signal flows.

The record path includes an integrated microphone bias circuit

and six inputs. The inputs can be mixed and muxed before the

ADC, or they can be configured to bypass the ADC. The

ADAU1761 includes a stereo digital microphone input.

The ADAU1761 includes five high power output drivers (two

differential and three single-ended), supporting stereo head-

phones, an earpiece, or other output transducer. AC-coupled

or capless configurations are supported. Individual fine level

controls are supported on all analog outputs. The output mixer

stage allows for flexible routing of audio.
