Analog Devices announced four fixed point digital signal processors qualified for automotive applications. Designed to fit the emerging demands of new and improved audio algorithms, the ADAU1466 and ADAU1467 SigmaDSP processors offer market-leading performance in fixed point DSP processors with three times the internal program memory and two times the internal data memory of the previous generation.

The ADAU1463 and ADAU1467 utilize an 88-pin LFCSP package and feature eight pins that can be configured as serial data inputs or outputs. These additional pins provide greater flexibility in amplifier or head unit designs to support applications such as hands free, active noise cancellation, and acoustic noise reduction among others. Like all SigmaDSP processors, the ADAU1463 and ADAU1467 feature a unique hardware architecture optimized for efficient audio processing. Their quad Multiply-Accumulate (MAC) architecture includes audio specific hardware accelerators that optimize MIPS performance for latency sensitive applications.

The ADAU146x series uses ADI's SigmaStudio graphical programming tool that allows signal flows and applications to be developed and tuned quickly and with a minimum learning curve (more info).
