Discover How Akustica Revolutionizes the Way You Hear

Thank you for your interest in the AKU2xxx family of digital-output microphones from Akustica.

What are digital microphones?

Akustica’s digital-output microphones are designed and manufactured using our revolutionary CMOS MEMS technology which enables the integration of the microphone transducer along with an amplifier and a sigma-delta converter all on a single piece of silicon.

Akustica’s small, surface mountable digital-output microphones:

• Provide high-quality audio input for telephony, recording, and speech recognition applications
• Save space
• Reduce power
• Lower component count
• Cut costs in manufacturing
• Reduce design time

Benefits of digital microphones?

As mobile phones and other consumer electronic devices continue to integrate more functionality and additional wireless capabilities into smaller and smaller products, the need for microphones that can scale down in size and can be placed in the best acoustic location without regard for the surrounding components will become more and more critical. Since the robust digital output of the microphones is immune to radio frequency (RF) and electromagnetic (EM) interference from nearby components such as antennas and displays, digital microphones are ideal for these applicatons.

The end result is thinner, cooler phones and consumer products with acoustic quality that will delight users!

Mobile Phone and Consumer Electronics Reference design

Akustica and TI have worked together to develop a reference design for use in mobile phones and other consumer electronic devices. The AKU2xxx-Module-B is a microphone array evaluation board with a direct connection to the TLV320AIC33/3106/34 evaluation board.
