CAS200 构成了Silicon Sensing的一系列双轴加速度计

CAS200和CAS290构成了Silicon Sensing的一系列双轴加速度计，在一个小的表面安装封装中提供高性能线性加速度测量。CAS200安装在电路板上，而CAS290版本安装在其侧面，这使得三个自由度的测量可以用一块电路板(PCBA)进行。
每个器件包括一个双轴MEMS传感器件和专用控制ASIC，封装在一个密封的陶瓷芯片规模封装中。测量数据和设备温度通过模拟和数字(SPI®)接口输出。
额外的内置测试(BIT)状态可从数字接口获得。有五个测量范围;±0.85g，±2.5g，±10g，±30g，±96g。精 确的线性加速度传感是通过MEMS结构形成一对正交的簧载防质量来实现的。

每个质量提供一个可变电容器的移动板，由一组交错的“手指”组成。这种结构提供了防止共振增益的关键阻尼。线性加速度导致电容的变化，这是通过解调方波激励来测量的。
每个设备都使用Silicon Sensing内部zui先进的测试设施进行设置和测试。Silicon Sensing Systems是硅MEMS陀螺仪，加速度计和惯性测量系统的市场领 导者，专注于高性能，可靠性和可负担性。凭借在惯性传感方面的强大传统，可以追溯到100多年前，所有传感器都基于内部专 利设计，这些设计是在其自己zui先进的MEMS铸造厂生产的。Silicon Sensing已经为全球数千家满意的客户提供了超过4000万个传感器，并通过技术专长和持续创新继续推动性能。

The CAS200 and CAS290 form Silicon Sensing's family of two-axis accelerometers that provide high-performance linear acceleration measurement in a small surface-mounted package. The CAS200 is mounted on a circuit board, while the CAS290 version is mounted on its side, which allows measurements of three degrees of freedom to be made with a single circuit board (PCBA).
Each device includes a two-axis MEMS sensor piece and dedicated control ASIC, packaged in a sealed ceramic chip-scale package. Measurement data and device temperature are output through analog and digital (SPI®) interfaces.
Additional built-in test (BIT) status is available from the digital interface. There are five measuring ranges; ±0.85g, ±2.5g, ±10g, ±30g, ±96g. Accurate linear acceleration sensing is achieved by forming a pair of orthogonal sprung guard masses in a MEMS structure.

Each mass provides a moving plate of variable capacitors, consisting of an interlaced set of "fingers." This structure provides critical damping to prevent resonance gain. Linear acceleration results in a change in capacitance, which is measured by demodulated square-wave excitation.
Each device is set up and tested using Silicon Sensing's state-of-the-art in-house testing facilities. Silicon Sensing Systems is a market leader in silicon MEMS gyroscopes, accelerometers and inertial measurement systems with a focus on high performance, reliability and affordability. With a strong heritage in inertial sensing dating back more than 100 years, all sensors are based on in-house patented designs that are produced at its own state-of-the-art MEMS foundry. Silicon Sensing has delivered more than 40 million sensors to thousands of satisfied customers worldwide and continues to drive performance through technical expertise and continuous innovation.
