ADAU1702JSTZ: SigmaDSP(R) 28-/56-Bit Audio Processor with Two ADCs and Four DACs

The ADAU1702 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 and can be used to compensate for real-world limitations of speakers, amplifiers, and listening environments, providing a dramatic improvements of 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 performance. The ADAU1702 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.

ADAU1702 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 ADAU1702 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 ADAU1702 communicates through an I^2C(R) bus or a 4-wire SPI(R) port.
