Integrated audio codec with silicon audio transducer

Image Number 7 for United States Patent #7929714.

An integrated audio transducer with associated signal processing electronics is disclosed. A silicon audio transducer, such as a MEMS microphone or speaker, can be integrated with audio processing electronics in a single package. The audio processing electronics can be configured using control signals. The audio processing electronics can provide a single line serial data interface and a single line control interface. The audio transducers can be integrated with associated processing electronics. A silicon microphone can be integrated with an Analog to Digital Converter (ADC). The ADC output can be a single line serial interface. The ADC can be configured using a single line serial control interface. A speaker may be integrated with a Digital to Analog Converter (DAC). Audio transducers can also be integrated with more complex processing electronics. Audio processing parameters such as gain, dynamic range, and filter characteristics may be configured using the serial interface.
