The ADAU1761BCPZ is a low power Stereo Audio Codec with an integrated digital audio processing that supports stereo 48kHz record and playback at 14mW from a 1.8V analog supply. The stereo audio ADCs and DACs supports sample rates from 8 to 96kHz as well as a digital volume control. The SigmaDSP? core features 28-bit processing (56-bit double precision). The processor allows system designers to compensate for the real-world limitations of microphones, speakers, amplifiers and listening environments, resulting in a dramatic improvement in the perceived audio quality through equalization, multiband compression, limiting and third-party branded algorithms. The SigmaStudio? graphical development tool is used to program the ADAU1761. This software includes audio processing blocks such as filters, dynamics processors, mixers and low level DSP functions for fast development of custom signal flows.
