ADAU1701JSTZ Overview

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.

Applications
  • Multimedia speaker systems
  • MP3 player speaker docks
  • Automotive head units
  • Minicomponent stereos
  • Digital televisions
  • Studio monitors
  • Speaker crossovers
  • Musical instrument effects processors
  • In-seat sound systems (aircraft/motor coaches)
