New Inertial-Grade MEMS Capacitive Accelerometers Feature Internal Temperature Compensation
Silicon Designs, Inc. (www.SiliconDesigns.com), a 100% veteran owned, U.S. based leading designer and manufacturer of highly rugged MEMS capacitive accelerometer chips and modules, today announced the immediate availability of its Model 1525 Series, a family of commercial and inertial-grade MEMS capacitive accelerometers, offering industry-best-in-class low-noise performance.
Design of the Model 1525 Series incorporates Silicon Designs’ own high-performance MEMS inertial capacitive sense element, along with a ±4.0V differential analog output stage, internal temperature sensor and integral sense amplifier -- all housed within a miniature, nitrogen damped, hermetically sealed, surface mounted J-lead LCC-20 ceramic package (U.S. Export Classification ECCN 7A994). The 1525 Series features low-power (+5 VDC, 5 mA) operation, excellent in-run bias stability, and zero cross-coupling. Five unique full-scale ranges, of ±2 g, ±5 g, ±10 g, ±25 g, and ±50 g, respectively, are currently in production and available for immediate customer shipment. Each Silicon Designs inertial-grade MEMS capacitive accelerometer offers reliable performance over a standard operating temperature range of -40° C to +85° C. Units are also relatively insensitive to wide temperature changes and gradients. Each device is marked with a serial number on its top and bottom surfaces for traceability. A calibration test sheet is also supplied with each unit, showing measured bias, scale factor, linearity, operating current, and frequency response data.
Carefully regulated manufacturing processes ensure that each sensor is made to be virtually identical, allowing users to swap out parts in the same g range with few-to-no testing modifications, further saving time and resources. This provides test engineers with a quick plug-and-play solution for almost any application, with total trust in sensor accuracy when used within published specifications. As the OEM of its own MEMS capacitive accelerometer chips and modules, Silicon Designs further ensures the manufacture of consistently high-quality products, with full in-house customization capabilities to customer exacting standards. This flexibility ensures that Silicon Designs can expeditiously design, develop and manufacture high-quality standard and custom MEMS capacitive accelerometers, yet still keep prices highly competitive.
The Model 1525 MEMS capacitive accelerometer series is ideal for zero-to-medium frequency inertial-grade instrumentation applications requiring high-repeatability, low noise, and maximum stability. Typical applications include, though may not be limited to, tactical guidance systems, navigation and control systems (GN&C), AHRS, unmanned aerial vehicles (UAVs), unmanned ground vehicles (UGVs), remotely operated vehicles (ROVs), robotic controllers, flight control systems, and marine- and land-based navigational systems. They may also be used to support industrial-grade testing requirements, such as agricultural vehicle and equipment instrumentation, oil and gas drilling, photographic and meteorological drones, and seismic applications.
Since 1983, the privately held Silicon Designs has served as leading industry experts in the design, development and manufacture of highly rugged MEMS capacitive accelerometers and chips with integrated amplification, operating from its own state-of-the-art facility near Seattle, Washington, USA. From the company’s earliest days of developing classified components for the United States Navy under a Small Business Innovation and Research (SBIR) grant, to its later Tibbetts Award and induction into the Space Technology Hall of Fame, Silicon Designs applies nearly 35 years of MEMS R&D innovation and applications engineering expertise into all finished product designs.

About Silicon Designs, Inc. Silicon Designs was founded in 1983 with the goal of improving the accepted design standard for traditional MEMS capacitive accelerometers. At that time, industrial-grade accelerometers were bulky, 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, though which also offered higher performance. Resultant product lines were designed and built to surpass customer expectations. The company has grown steadily over the years, while its core competency remains accelerometers, with the core business philosophies of “make it better, stronger, smaller and less expensive” and “let the customer drive R&D” maintained to this day.
