ADAU1445/ADAU1446
Rev. A | Page 3 of 92
GENERAL DESCRIPTION
The ADAU1445/ADAU1446 are enhanced audio processors that
allow full flexibility in routing all input and output signals. The
SigmaDSP core features full 28-bit processing (56-bit in double-
precision mode), synchronous parameter loading for ensuring
filter stability, and 100% code efficiency with the SigmaStudio
tools. This DSP allows system designers to compensate for the
real-world limitations of speakers, amplifiers, and listening
environments, resulting in a dramatic improvement of the
perceived audio quality through speaker equalization, multi-
band compression, limiting, and third-party branded algorithms.
The flexible audio routing matrix (FARM) allows the user to
multiplex inputs from multiple sources running at various
sample rates to or from the SigmaDSP core. This drastically
reduces the complexity of signal routing and clocking issues in
the audio system. FARM includes up to eight stereo asynchronous
sample rate converters (depending on the device model), Sony/
Philips Digital Interconnect Format (S/PDIF) input and output,
and serial (I2S) and time division multiplexing (TDM) I/Os. Any of
these inputs can be routed to the SigmaDSP core or to any of the
asynchronous sample rate converters (ASRCs). Similarly, any one
of the output signals can be taken from the SigmaDSP core or
from any of the ASRC outputs. This routing scheme, which can
be modified at any time via control registers, allows for maximum
system flexibility.
The ADAU1445 and ADAU1446 differ only in ASRC functionality
and packaging. The ADAU1445 contains 16 channels of ASRCs
and is packaged in a TQFP, whereas the ADAU1446 contains no
ASRCs and is packaged in an LQFP.
The ADAU1445/ADAU1446 can be controlled in one of two
operational modes. First, the settings of the chip can be loaded
and dynamically updated through the SPI/I2C port. Second, the
DSP can self-boot from an external EEPROM in a system with
no microcontroller. There is also a bank of multipurpose (MP) pins
that can be used as general-purpose digital I/Os or as inputs to
the 4-channel auxiliary control ADC.
The ADAU1445/ADAU1446 are supported by the SigmaStudio
graphical development environment. This software includes
audio processing blocks such as FIR and IIR filters, dynamics
processors, mixers, low level DSP functions, and third-party
algorithms for fast development of custom signal flows.
