Analogue to digital convertors (ADCs) are used to convert analogue signals, such as audio signals, to digital numbers (digital signals).

Audio Amplifiers

These are electronic amplifiers that amplify low power audio signals, in the 20Hz to 20kHz band, to a level suitable for driving a loudspeaker or headset.


Integrate all the audio functionality such as signal routing, mixing, converting and amplifying onto a single audio centric device to give consistent high definition audio quality across different applications and tiers.


Digital to analogue converters (DACs) perform the opposite function of the ADC by converting the digital signal back to the analogue domain (audio signal) ready for playback via loudspeakers or headsets.

MEMS Microphones

Micro-electro-mechanical systems (MEMS) microphones offer a unique combination of high performance and compact form factor to enable crystal clear audio capture. The close tolerance sensitivity makes them ideal for multi-microphone applications such as noise cancellation and speakerphone.

Power Management

Power management integrated circuits (PMICs) intelligently manage and optimise the use of power within the system architecture to maximise battery life in portable devices.

S/PDIF Transceivers

These Sony/Philips Digital Interface devices send and receive digital audio signals over coaxial (or fibre optic) cable to interconnect home audio products.


The selection of advanced audio algorithms allows customers to select differentiating features for their products from noise cancellation to sound enhancement.
