Patent ID: 7929714

Claim:
A transducer system comprising: an integrated circuit carrier; a transducer comprising a semiconductor die; and a transducer electronics die configured to provide one or more functions, coupled to the transducer, mounted on the integrated circuit carrier, and encapsulated within a package, the transducer electronics die comprising an amplifier in direct communication with the transducer, the transducer electronics die having transducer electronics configured to provide a digital transducer interface comprising a serial data interface, a serial control interface, and a clock input, wherein the serial control interface is configured to receive a control signal that selectively controls a gain of the amplifier, wherein the transducer electronics die further comprises a digital signal processor (DSP) in communication with the amplifier, and wherein the DSP is configured to implement a CODEC for compressing audio data from the transducer or wherein the DSP is configured to implement a CODEC for decompressing audio data being supplied to the transducer, wherein the transducer is implemented separate from and external to the transducer electronics die and encapsulated within the package; and wherein the semiconductor die is stack mounted on the transducer electronics die.
