GENERAL DESCRIPTION
The ADAU1461 is a low power, stereo audio codec with
integrated digital audio processing that supports stereo 48 kHz
record and playback at 35 mW from a 3.3 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 ADAU1461. 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
ADAU1461 includes a stereo digital microphone input.
The ADAU1461 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.
