MEV-50A-R 車載陀螺儀

一個的基于MEMS技術的汽車導航系統的陀螺儀傳感器裝置已經宣布村田，提供性能和制造優勢，比傳統方法。 

Newy Electronics Co.,ltd

構造一個系統級封裝（SiP）中，該微機電系統（MEMS）器件包含一個基于硅片振動的設備和設計的電容式傳感器電路集成電路自定義。The two chips are mounted on a ceramic substrate, and then hermetically sealed in a ceramic surface mount package.這兩款芯片安裝在陶瓷基板，然后密封在一個密封的陶瓷表面貼裝封裝。

Both devic are manufactured using proven and cost-effective production procs, to provide high reliability and ior performance at a low cost.這兩種設備都采用成熟和成本效益的生產過程，提供高性和卓越性能。From the OEM's perspective, Murata's MEV-50A-R gyro sensor is a compact, hermetically sealed, surface mount, ceramic device contained in a fully RoHS compliant package measuring just 10mm x 10mm, with a profile of 3.3mm.從OEM的角度來看，村田的兆電子伏特- 50A條- R的陀螺儀傳感器是一種緊湊，密封，表面貼裝，陶瓷器件合RoHS標準，尺寸只有10 x 10mm的包中包含的和3.3毫米配置。It is qualified to the –40°C to +85°C temperature range, making it ideal for automotive applications.它有資格為-40 ° C至+85 ° C溫度范圍，適用于汽車應用。

Murata's gyro sensor us Coliolis force principle of detecting angular velocity, whereby four m are positioned between two driving beams.村田的陀螺傳感器采用檢測角速度，即4個群眾是兩個驅動力量的原則定位Coliolis橫梁。By flexing the driving beams, the m are vibrated along the x-axis.通過伸縮駕駛橫梁，人民群眾是振動沿x軸。Then, when angular velocity is applied, two detecting m are vibrated along the y-axis, producing a rotation in the opposite direction to the Coliolis force.然后，當角速度應用，人民群眾是兩個振動檢測沿y軸，產生相反的方向轉動的Coliolis力量。

This technique rults in lower acceleration noise, when compared to acceleration techniqu, as the capacitive variations are cancelled out.加速噪音低，這種技術的結果相比，加速技術，因為電容變化被取消了。Further, the device us dial signal compensation to deliver low offset drift over the temperature range.此外，該器件采用了數字信號的補償，以提供溫度范圍低失調漂移。

Featur include fast rponse, low driving voltage and low current consumption.其功能包括快速響應，低驅動電壓和低電流消耗。Technical specifications over the –40°C to +85°C operating temperature range include: linearity error of –0.5% to +0.5% FS; output noise of 10mV peak to peak; start up drift of –0.4 to +0.4degre/s from 1s to 5mins and –0.8 to +0.8degre/s from 1s to 15min; and frequency rponse (frequency vs gain) of –4dB to –1dB with gain at 7Hz.技術規格工作在-40 ° C至+85 ° C的工作溫度范圍包括：線性度0.5％，財政司司長誤差-0.5％; 10mV的輸出峰值噪音;啟動的0.4至0.4度漂移/秒從1秒至5分鐘和-0.8至+0.8度/秒，從1秒至15分鐘;及頻率響應（頻率對增益）的同在7Hz增益四分貝到1dB的。

Full technical data and applications guidance is readily available from the Murata website.充分的技術數據和應用程序的指導很容易從村田網站上查閱。It outlin, for example, that a minimum of external circuitry is required along with the 5V power regulator and A/D converter, to integrate the gyro sensor device.它概述例如，外部電路少需要隨著5V電源穩壓器和A / D轉換器，集成了陀螺儀傳感器裝置。The include noise elimination capacitors on the power supply, a 100kohm load ristor, and a seri ristor, depending on the line distance between Vout and the A/D converter.這些措施包括對電源，100k歐姆負載電阻電容消除噪音，并根據與輸出電壓之間的一條線的距離/ D轉換器一個串聯電阻。
