AD1940YSTZRL: SigmaDSPTM Multichannel 28-Bit Audio Processor LQFP-48封装

The AD1940 is a complete 28-bit, single-chip, multichannel audio DSP for equalization, multiband dynamics processing, delay compensation, speaker 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 AD1940 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 dynamics processor uses a sophisticated, multiple-breakpoint algorithm often found in high end broadcast compressors.

The AD1940 is a fully-programmable DSP. Easy-to-use software allows the user to graphically configure a custom signal processing flow using blocks such as biquad filters, dynamics processors, and surround sound processors. An extensive control port allows click-free parameter updates, along with readback capability from any point in the algorithm flow.

The AD1940’s digital input and output ports allow a glueless connection to ADCs and DACs by multiple, 2-channel serial data streams or TDM data streams. When in TDM mode, the AD1940 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. The AD1940 is controlled via a 4-wire SPI port.
