SAN JOSE, Calif.–(BUSINESS WIRE)–Feb. 22, 2016– InvenSense, a leading provider of MEMS sensor platform solutions, announces the availability of the ICS-43434 providing the most efficient audio path for space-constrained wearables and Internet of Things (IoT) devices. InvenSense's new ICS-43434 I²S Microphone provides 65% power savings in its low-power mode compared to existing solutions while delivering excellent acoustic performance targeted to IoT and Wearable applications.

Providing a direct digital I²S interface to the main application processor, the ICS-43434 eliminates the need for the CODEC in smartphones commonly used with analog microphones. This approach saves area and reduces power consumption, especially critical to a wearable design where small board space and small battery are important to enabling a small form factor. The ICS-43434 acoustical properties have also been optimized for wearable and IoT applications where high sensitivity is needed to listen for the user's command as the main means of communication in a low-power state. The InvenSense ICS-43434 is able to maintain this high acoustic sensitivity while at the same time, it avoids acoustical distortion or voice that can happen when the user brings a wearable device close for voice command in a noisy environment such as a concert. This combination of system efficiency along with targeted-acoustical properties results in industrial designs that are functional and elegant at the same time.

"InvenSense continues to be committed to introducing disruptive, high-performance, and innovative Audio solutions into the market," said Eitan Medina vice president of marketing and product management, InvenSense. "The new ICS-43434 provides the most flexible and efficient system design, enabling our OEM partners to create a differentiated audio experience where audio is the main means of communication with the device."

The ICS-43434 is sampling now with MP quantities available in Q2 2016.
