General Description

The AD1954 is a complete 26-bit single-chip 3-channel digital audio playback system with built-in DSP functionality for speaker equalization, dual-band compression/limiting, delay compensation, and image enhancement.

These algorithms can be used to compensate for real-world limitations of speakers, amplifiers, and listening environments, resulting in a dramatic improvement of perceived audio quality.

The signal processing used in the AD1954 is comparable to that found in high-end studio equipment.

Key Features

  • 5 V 3-Channel Audio DAC System Accepts Sample Rates up to 48 kHz 7 Biquad Filter Sections per Channel Dual Dynamic Processor with Arbitrary Input/Output Curve and Adjustable Time Constants 0 ms to 6 ms Variable Delay/Channel for Speaker Alignment Stereo Spreading Algorithm for Phat Stereo™ Effect Program RAM Allows Complete New Program Download via SPI Port Parameter RAM Allows Complete Control of More Than 200 Parameters via SPI Port SPI Port Features Safe-Upload Mode for Transparent Filter Upd.
