GENERAL DESCRIPTION
The ADAU1701 is a complete single-chip audio system with a
28-/56-bit audio DSP, ADCs, DACs, and microcontroller-like
control interfaces. Signal processing includes equalization, cross-
over, bass enhancement, multiband dynamics processing, delay
compensation, speaker compensation, and stereo image widening.
This processing can be used to compensate for real-world
limitations of speakers, amplifiers, and listening environments,
providing dramatic improvements in perceived audio quality.
Its signal processing is comparable to that found in high end
studio equipment. Most processing is done in full 56-bit, double
precision mode, resulting in very good low level signal perfor-
mance. The ADAU1701 is a fully programmable DSP. The easy to
use SigmaStudio software allows the user to graphically configure
a custom signal processing flow using blocks such as biquad filters,
dynamics processors, level controls, and GPIO interface controls.
ADAU1701 programs can be loaded on power-up either from a
serial EEPROM through its own self-boot mechanism or from
an external microcontroller. On power-down, the current state
of the parameters can be written back to the EEPROM from the
ADAU1701 to be recalled the next time the program is run.
Two Σ-Δ ADCs and four Σ-Δ DACs provide a 98.5 dB analog
input to analog output dynamic. Each ADC has a THD + N of
83 dB, and each DAC has a THD + N of 90 dB. Digital input
and output ports allow a glueless connection to additional
ADCs and DACs. The ADAU1701 communicates through an
I2C bus or a 4-wire SPI port.
