GA50 Accelerometer
Single Axis, MEMS Open Loop Accelerometer
The GA50 series high-end open loop MEMS accelerometers are available in various sensing ranges. The accelerometer is based on a bulk micro-machined silicon MEMS device and an application-specific integrated circuit (ASIC) with an analog front end (AFE) and a temperature sensor, assembled in a custom-tailored, hermetically sealed, and compact LCC20 package. The robust, low-power GA50 accelerometer delivers superior long term bias repeatability and stability. It is ideal for Aerospace & Defense applications including Inertial Measurement Units (IMUs), and other demanding guidance, navigation, autonomous, and seismic applications.
Overview
- Multiple G Ranges
The GA50 Accelerometers are available in 5g, 40g, 70g, ranges, allowing you to have the solution best tailored to your needs.
- Extremely Small Size
The GA50 Accelerometers are compact (253 mm³ or 0.25 cm³) LCC20 package, the GA50 is our smallest MEMs device yet.
- Available on Evaluation Board
The GA50 Accelerometers are customizable for a wide range of applications and can be delivered individually or mounted on an evaluation board for simplified testing.
