Abstract
An audio system 100 disposed on a single chip includes an output mixer 115 having inputs for receiving first digital audio data of a first bit width from a first digital-to-analog converter 110, digital audio data of a second bit width from a second digital-to-analog converter 6601, and analog data from an external port. An output port drives an analog signal output from the output mixer. An input mixer 114 has inputs for receiving analog data from a plurality of sources and analog-to-digital converters 111 to convert an analog output from the input mixer into digital data. An input path transmits the digital data output from the analog to digital convertors 111 to an external digital bus.
