Lower-cost MEMS accelerometer modules for inertial navigation

ISO9001:2015 certified, 100% US veteran-owned designer and manufacturer of rugged industrial-grade MEMS capacitive accelerometer chips, modules, and supporting data acquisition, Silicon Designs, has introduced its Model 2227-025, the first in a planned family of high-performance, lower-cost MEMS accelerometer modules for inertial navigation and tilt applications (non-ITAR).

The Model 2227-025 has both an industry standard form factor and pin compatibility with many of the quartz-based accelerometers currently used in these applications. This allows the Model 2227-025 to serve as both a lower-cost alternative and direct drop-in replacement for many industry quartz-based inertial navigation accelerometers.

The rugged design of the Model 2227-025 MEMS accelerometer module combines two patented, capacitive, silicon sense elements (US Patent Number 4,736,629), together with a precision, custom CMOS integrated circuit, in a compact, low mass, hermetically sealed LCC package. These ±25 g modules are assembled on a high-temperature open printed circuit board (PCB) with a circuit that converts the differential output voltage of the MEMS accelerometer into a current directly proportional to the amount of applied acceleration. 

This design allows the Model 2227-025 to achieve the low-noise, high-stability, long-term repeatability and low power needed for many of today’s inertial navigation applications. Final testing is conducted on a temperature-tumble-system, thereby providing thermal calibration parameters that simplify accelerometer use with the customer’s own real-time temperature compensation and model ling software.

Test samples of the Model 2227-025 are immediately available for customer evaluation in North America and the United Kingdom. Two additional g-ranges, to be sold as the Model 2227-010 (±10g) and Model 2227-050 (±50g), respectively, have anticipated availability starting in January 2019.
