The ADAU1452 / ADAU1451 / ADAU1450 are automotive qualified audio processors that far exceed the digital signal processing capabilities of earlier SigmaDSP® devices. The restructured hardware architecture is optimized for efficient audio processing. The audio processing algorithms are realized in sample-by-sample and block-by-block paradigms that can both be executed simultaneously in a signal processing flow created using the graphical programming tool, SigmaStudio™. The restructured digital signal processor (DSP) core architecture enables some types of audio processing algorithms to be executed using significantly fewer instructions than were required on previous SigmaDSP generations, leading to vastly improved code efficiency.The 1.2 V, 32-bit DSP core can run at frequencies of up to 294.912 MHz and execute up to 6144 instructions per sample at the standard sample rate of 48 kHz. However, in addition to industry-standard rates, a wide range of sample rates are available. The integer PLL and flexible clock generator hardware can generate up to 15 audio sample rates simultaneously. These clock generators, along with the on-board asynchronous sample rate converters (ASRCs) and a flexible hardware audio routing matrix, make the ADAU1452 / ADAU1451 / ADAU1450 ideal audio hubs that greatly simplify the design of complex multirate audio systems.The ADAU1452 / ADAU1451 / ADAU1450 interface with a wide range of analog-to-digital converters (ADCs), digital-to-analog converters (DACs), digital audio devices, amplifiers, and control circuitry, due to their highly configurable serial ports, S/PDIF interfaces (on the ADAU1452 and ADAU1451), and multipurpose input/output pins. The devices can also directly interface with pulse density modulation (PDM) output microelectromechanical (MEMS) microphones, due to integrated decimation filters specifically designed for that purpose.Independent slave and master I2C/serial peripheral interface (SPI) control ports allow the ADAU1452 / ADAU1451 / ADAU1450 not only to be programmed and configured by an external master device, but also to act as masters that can program and configure external slave devices directly. This flexibility, combined with self boot functionality, enables the design of standalone systems that do not require any external input to operate.The power efficient DSP core executes full programs, consumes only a few hundred milliwatts (mW) of power, and can run at a maximum program load while consuming less than a watt, even in worst case temperatures exceeding 100°C. This relatively low power consumption and small footprint make the ADAU1452 / ADAU1451 / ADAU1450 ideal replacements for large, general-purpose DSPs that consume more power at the same processing load.Differences between the ADAU1452, ADAU1451, and ADAU1450The five variants of this device are differentiated by memory, DSP core frequency, availability of S/PDIF interfaces, ASRC configuration, and temperature range.Because the ADAU1450 does not contain an S/PDIF receiver or transmitter, the SPDIFIN and SPDIFOUT pins are nonfunctional. Additionally, the settings of any registers related to the S/PDIF input or output in the ADAU1450 do not have any effect on the operation of the device.Because the ADAU1450 does not contain ASRCs, the settings of any registers related to the ASRCs in the ADAU1450 do not have any effect on the operation of the device.APPLICATIONS Automotive audio processing Head units Navigation systems Rear seat entertainment systems DSP amplifiers (sound system amplifiers) Commercial and professional audio processing Consumer audio processing
