Silicon Designs releases Model 1525 series of commercial and inertial-grade MEMS capacitive accelerometers

Silicon Designs, Inc. a designer and manufacturer of MEMS capacitive accelerometer chips and modules, announced the availability of its Model 1525 Series, a family of commercial and inertial-grade MEMS capacitive accelerometers.

Design of the Model 1525 Series incorporates Silicon Designs’ own MEMS variable capacitive sense element, along with a ±4.0V differential analog output stage, internal temperature sensor and integral sense amplifier — all housed within a nitrogen damped, hermetically sealed, surface mounted J-lead LCC-20 ceramic package (U.S. Export Classification ECCN 7A994). The 1525 Series features +5 VDC, 5 mA operation, in-run bias stability, and zero cross-coupling. Five full-scale ranges, of ±2 g, ±5 g, ±10 g, ±25 g, and ±50 g, are currently in production and available for immediate customer shipment. Each MEMS accelerometer offers performance over a standard operating temperature range of -40° C to +85° C. Each device is marked with a serial number on its top and bottom surfaces for traceability. A calibration test sheet is supplied with each unit, showing measured bias, scale factor, linearity, operating current, and frequency response.

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. This provides test engineers with a plug-and-play solution for almost any application.

The Silicon Designs Model 1525 Series tactical grade MEMS inertial accelerometer family is designed for zero-to-medium frequency instrumentation applications that require high-repeatability, low noise, and stability, including 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 critical industrial test requirements, such as those common to agricultural, oil and gas drilling, photographic and meteorological drones, as well as seismic and inertial measurements.
