Claim Text:
1. A microphone package comprising: a microphone; a first analog-to-digital converter coupled to the microphone to provide a first digital signal; a second analog-to-digital converter coupled to the microphone to provide a second digital signal; a circuit coupled to the first analog-to-digital converter and the second analog-to-digital converter to provide a microphone signal, wherein the circuit determines the microphone signal using a combination of the first digital signal, a first weighting coefficient, the second digital signal and a second weighting coefficient; and a controller configured to control a mode of operation of the circuit and to change the mode of operation when an input to the first analog-to-digital converter or the second analog-to-digital converter exceeds a predetermined threshold, the controller further being configured to determine the first weighting coefficient for the first digital signal and the second weighting coefficient for the second digital signal using a level of the input to the first analog-to-digital converter or the second analog-to-digital converter.
