The World's Smallest Microphone

It’s silicon, digital and with a tiny 3 cubic mm size - the new DigiSiMicTM fits perfectly into tomorrow’s mobile phones, PDAs, and headsets.

Sonion's DigiSiMic^TM microphone is the world's smallest digital silicon microphone. Sonion products, such as the DigiSiMic^TM help mobile phone manufacturers design smaller, lighter products with cost in mind.

"After more than a decade of research, the Sonion digital silicon microphone DigiSiMic^TM is a development breakthrough for the industry. It is a minute, feather light but still a very robust microphone that has stable high quality acoustic performance," said Jacob Philipsen, President of Sonion MEMS.

With a footprint of only 2.6 x 1.6 mm² the DigiSiMic^TM is ideal for applications where minimum microphone size is key.

As analogue electric condenser microphones (ECM) are the standard in today's mobile terminals with analogue silicon microphones emerging, the digital silicon microphone DigiSiMic^TM represents a technological leap towards the fully digitalized mobile phone architectures of "tomorrow".

Key features and benefits of the DigiSiMic^TM:

Size, all silicon package and surface mountability - ease manufacturing costs and increase efficiency.
Integrated Solution - Integrated microphone, analogue pre-amplifier and sigma-delta modulator reduce component count and board space, as well as RF/EM interference.
High Suppression of RF and EM Interference - Digital output eliminates EM interference over long transmission distances, enabling microphone arrays that increase performance.
Digitalization - Enables high performance microphone array applications.
Left/Right feature enabling stereo application over a single data wire.

In addition to Sonion's digital silicon micropone, the DigiSiMic™ , Sonion is also launching the SiMic™, the industry's smallest analogue microphone. The product brings an unparalleled level of performance and fidelity, including a typical signal-to-noise ratio of 61dB in a previously unachievable small package size with a footprint of only 2.4 x 1.6.
