Overview
The ADAU1761BCPZ-RL, produced by Analog Devices Inc., is a low-power, stereo audio codec with integrated digital audio processing. It supports stereo 48 kHz record and playback at 14 mW from a 1.8 V analog supply. This codec features a SigmaDSP core, which is a 28-/56-bit, 50 MIPS digital audio processor, allowing for advanced audio processing capabilities such as equalization, multiband compression, and limiting. The ADAU1761 is fully programmable using the SigmaStudio graphical development tool, enabling system designers to customize the audio signal flow efficiently.
