Abstract

A microphone package comprises a microphone. The microphone package also comprises a first analog-to-digital converter coupled to the microphone to provide a first digital signal. The microphone package further comprises a second analog-to-digital converter coupled to the microphone to provide a second digital signal. Furthermore, the microphone package comprises a circuit coupled to the first analog-to-digital converter and the second analog-to-digital converter to provide the microphone signal.

Description

technical field [0001] Various embodiments of the invention relate to a microphone package for providing a microphone signal and a method for providing a microphone package. Background technique [0002] Microphones are used to record external noise or sounds. Telecom applications often use small microphones. One example of a small microphone is a silicon microphone or a microphone implemented as a microelectromechanical system (MEMS). For some of today's applications, processing of sound levels as high as 140dB SPL must be achieved. This may increase the dynamic range covered by the signal path, which in turn affects the Application Specific Integrated Circuit (ASIC) configured to process the microphone signal. [0003] A conventional approach to meet higher requirements for increased dynamic range uses two analog-to-digital converters (ADCs). A coder / decoder (CODEC) determines an output signal from the first or second ADC, which is then used for further processing in a...
