FEATURES

SigmaDSP 28-/56-Bit Audio Processor

with Two ADCs and Four DACs

ADAU1701

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

C® bus or a 4-wire SPI port.

28-/56-bit, 50 MIPS digital audio processor

2 ADCs: SNR of 100 dB, THD + N of −83 dB

4 DACs: SNR of 104 dB, THD + N of −90 dB

Complete standalone operation

Self-boot from serial EEPROM

Auxiliary ADC with 4-input mux for analog control

GPIOs for digital controls and outputs

Fully programmable with SigmaStudio graphical tool

28-bit × 28-bit multiplier with 56-bit accumulator for full

double-precision processing

Clock oscillator for generating a master clock from crystal

PLL for generating master clock from 64 × f

, 256 × f

384 × f

, or 512 × f

clocks

Flexible serial data input/output ports with I

S-compatible,

left-justified, right-justified, and TDM modes

Sampling rates of up to 192 kHz are supported

On-chip voltage regulator for compatibility with 3.3 V systems

48-lead, plastic LQFP

APPLICATIONS
