AD1941YSTZRL:  SigmaDSP™ Multichannel 28-Bit Audio Processor LQFP-48封装

The AD1941 is a complete 28-bit, single-chip, multichannel audio DSP for speaker equalization, multiband compression/ limiting, delay compensation, and image enhancement. These algorithms can be used to compensate for the real-world limitations of speakers, amplifiers, and listening environments, resulting in a dramatic improvement of perceived audio quality.

The signal processing used in the AD1941 is comparable to that found in high-end studio equipment. Most of the processing is done in full 56-bit double-precision mode, resulting in very good low-level signal performance and the absence of limit cycles or idle tones. The compressor/limiter uses a sophisticated multiple-breakpoint algorithm often found in high-end broadcast compressors.

The AD1941 is a fully-programmable DSP. Easy-to-use software allows the user to graphically configure a custom signal processing flow with provided blocks such as biquad filters, dynamics processors, and surround sound processors. An extensive control port allows click-free parameter updates, along with read-back capability from any point in the algorithm flow.

The AD1941’s digital input and output ports allow glueless connection to ADCs and DACs in either 2-channel or TDM mode, and to digital amplifier power stages such as the AD1991. When in TDM mode, the AD1941 can input 8 or 16 channels of serial data, and can output either 8 or 16 channels of serial data. The input and output port configurations can be individually set.
