New Low-Mass Single Axis MEMS Capacitive Accelerometers Offer Enhanced Temperature Performance
Silicon Designs, Inc. (www.silicondesigns.com)(SDI), a 100% veteran owned and U.S. based global industry leader in the design, development and manufacture of highly rugged industrial-grade MEMS capacitive accelerometer chips, modules and supporting data acquisition, today announced the recently enhanced performance of its compact, low-mass, single axis Model 2220 series.
Design of the enhanced Model 2220 series incorporates Silicon Designs’ new proprietary high-performance MEMS capacitive chip, along with high-drive, low-impedance buffering, for industry-exclusive improved bias and scale factor over temperature performance. These specifications are unmatched among other industry MEMS capacitive accelerometer manufacturers, yet are still offered by Silicon Designs at a highly competitive price point.
The Silicon Designs 2220 series is available in seven unique models, in standard ranges from ±2 g to ±200 g, and each with a wide frequency response, down to zero hertz. Each Model 2220 Series MEMS capacitive accelerometer module further features an epoxy-sealed rugged anodized aluminum housing, with mounting achieved via two M3 screws. Its low mass (10 g) and compact size (1" x 1" x 0.3") can help to minimize mass loading effects. Non-standard g ranges, packages and connector configurations are available upon request.
Series modules are designed to respond to both DC and AC acceleration, either with two analog ±4V (differential); or 0.5 to 4.5V (single-ended) outputs that vary with acceleration. At zero acceleration, differential voltage output is nominally 0 VDC (DC response), with typical 1% cross-axis sensitivity. Onboard voltage regulation minimizes supply variation effects. Units are designed to withstand shock inputs of up to 2000 g over a standard temperature range of –55°C to +125°C. Each module is serialized for traceability and calibrated prior to factory shipment.
All Silicon Designs MEMS capacitive accelerometers, chips, and dies are 100% designed, manufactured, and tested at the company’s own state-of-the-art global corporate headquarters and R&D center, located in Kirkland, Washington, USA. This vertically integrated manufacturing approach allows the company to consistently offer high-quality products at competitive pricing, further delivered with some of the industry’s shortest lead times. Standard model quantities can typically ship in less than two weeks.
The combined low mass, small dimensional size, and low-impedance outputs of the Silicon Designs Model 2220 Series make it particularly ideal for flight test, aircraft flutter testing, vibration monitoring and analysis, robotics, biomechanics, automotive RLDA, machinery and equipment control, modal analysis, crash testing, and general in-laboratory applications.

About Silicon Designs, Inc. Silicon Designs (www.silicondesigns.com) was founded in 1983, with the goal of improving the accepted design standard for MEMS capacitive accelerometers. At that time, industrial-grade accelerometers on the market were bulky, highly fragile and costly. The engineering team at Silicon Designs listened to the needs of customers who required more compact, sensitive, rugged and reasonably priced accelerometer modules and chips that also offered higher performance. Resultant product lines were designed and built to surpass customer expectations. The company has grown steadily over the years, though its core competency remains accelerometers, with the business philosophy of “Make it better, stronger, smaller and less expensive” maintained to this day.
