Analog Devices Inc. ADAU1860/1860-1 Low Power Codecs with Audio DSPs

Analog Devices Inc. ADAU1860/1860-1 Low Power Codecs with Audio DSPs are codecs with three inputs and one output that incorporate two Digital Signal Processors (DSPs). These codecs optimize low latency and a programmable double-precision MAC engine for a maximum 24-stage equalizer. The ADAU1860/1860-1 codecs feature eight digital microphone inputs, 2 PDM output channels, and three differential or single-ended analog inputs configurable as microphone or line inputs. The ADAU1860 codec is only available for ordering by customers located in the People’s Republic of China (PRC). The ADAU1860-1 codec is available for ordering by customers outside the PRC. Typical applications include noise-canceling headsets and headphones, personal navigation devices, musical instrument effect processors, multimedia speaker systems, and smartphones.
