In 2009, Akustica was acquired by, and is now a wholly electronics device manufacturers. owned subsidiary of, Robert Bosch North America. As part of the Bosch Group, Akustica joins a family of In-house Design and Manufacturing: Unlike other companies with combined annual sales of more than $70 billion and a footprint of over 300,000 associates MEMS microphone manufacturers who buy their MEMS and/or ASIC die from a third party, Akustica maintains complete product knowledge by designing 100% of our MEMS microphones in-house. In addition, Akustica is the only MEMS microphone supplier to offer the security of in-house MEMS manufacturing via Bosch's world-renowned wafer fab in Reutlingen, Germany. Applications Expertise: The performance of modern microphone systems is heavily dependent on the overall platform design, including software algorithms, mechanical layout and hardware implementation. As an innovator in the field of MEMS microphones and leveraging over 10 years of experience, Akustica has a deep understanding of acoustic design requirements worldwide. Bosch has been active in the field of MEMS since 1988 and is one of the pioneers in microsystem-technology. Bosch serves both the automotive and consumer electronics markets, and is the only MEMS supplier to design and manufacture all of its own MEMS for its complete portfolio of inertial, pressure, magnetic, and acoustic MEMS sensors for consumer devices. With more than five billion MEMS sensors shipped worldwide since 1993, Bosch is the world's leading supplier of MEMS sensors. Ordering Information and proper analysis methods. To ensure our customers a seamless integration experience and Part Number AKU151 Description Analog MEMS Microphone support constrained design cycles, Akustica offers acoustic design and modeling services prior to Package 4 Pad LGA Shipping Method 13" Reel assembly. Akustica also provides production test services, training, and test equipment to help ensure Standard Quantity 5900 the quality of both incoming and final assembled products.
