Part Details:

SigmaDSP® 28-/56-Bit Audio Processor with Two ADCs and Four DACs ADAU1702 FEATURES GENERAL DESCRIPTION 28-/56-bit, 25 MIPS digital audio processor The ADAU1702 is a complete single-chip audio system with a Two ADCs: SNR of 100 dB, THD + N of -83 dB 28-/56-bit audio DSP, ADCs, DACs, and microcontroller-like Four DACs: SNR of 104 dB, THD + N of -90 dB control interfaces. Signal processing includes equalization, cross- Complete standalone operation Self-boot from serial EEPROM over, bass enhancement, multiband dynamics processing, delay Auxiliary ADC with 4-input mux for analog control compensation, speaker compensation, and stereo image widening GPIOs for digital controls and outputs and can be used to compensate for real-world limitations of Fully programmable with SigmaStudioTM graphical tool speakers, amplifiers, and listening environments, providing a 28-bit × 28-bit multiplier with 56-bit accumulator for full dramatic improvements of perceived audio quality. double-precision processing Clock oscillator for generating master clock from crystal Its signal processing is comparable to that found in high PLL for generating master clock from 64 × fS, 256 × fS, end studio equipment. Most processing is done in full 56-bit, 384 × fS, or 512 × fS clocks double-precision mode, resulting in very good low level signal Flexible serial data input/output ports with I2S-compatible, performance. The ADAU1702 is a fully programmable DSP. The left-justified, right-justified, and TDM modes Sampling rates up to 192 kHz supported easy to use SigmaStudio software allows the user to graphically On-chip voltage regulator for compatibility with 3.3 V systems configure a custom signal processing flow using blocks such as 48-lead, plastic LQFP biquad filters, dynamics processors, level controls, and GPIO interface controls. APPLICATIONS Multimedia speaker systems ADAU1702 programs can be loaded on power-up either from a MP3 player speaker docks serial EEPROM through its own self-boot mechanism or from Automotive head units an external microcontroller. On power-down, the current state Minicomponent stereos of the parameters can be written back to the EEPROM from the Digital televisions ADAU1702 to be recalled the next time the program is run. Studio monitors Speaker crossovers Two - ADCs and four - DACs provide a 98.5 dB analog Musical instrument effects processors input to analog output dynamic. Each ADC has a THD + N of In-seat sound systems (aircraft/motor coaches)
