Invensense推出IDG-650/ ISZ-650應(yīng)用游戲搖桿陀螺儀

富威集團(tuán)代理產(chǎn)線(xiàn)Invensense推出IDG-650/ ISZ-650,增加運(yùn)動(dòng)傳感之游戲機(jī)臺(tái)與手持游戲機(jī)，增添了新的互動(dòng)空間。要求近乎真實(shí)情境的1：1游戲新體驗(yàn)，便需要游戲處理技術(shù)(多軸陀螺儀與其他傳感器之結(jié)合運(yùn)用)。應(yīng)用于游戲搖桿的陀螺儀，提供關(guān)鍵性旋轉(zhuǎn)資訊，并不像磁場(chǎng)計(jì)或加速器般易受干擾。為改進(jìn)新的Wii Motion Plus配件之運(yùn)動(dòng)處理功能，任天堂引用了InvenSense的多軸陀螺儀，使反應(yīng)更快，并實(shí)現(xiàn)了準(zhǔn)確的3D游戲手勢(shì)追緃。

如同Wii Motion Plus，應(yīng)用于游戲之陀螺儀的主要要素為寬廣的全格傳感范圍(wide full scale range)、高軸間隔絕(high cross-axis isolation)、極佳震動(dòng)排除(superior vibration rejection)、高機(jī)械碰撞容忍度(high mechanical shock tolerance)，以及小尺寸。InvenSense的IDG-650可完全滿(mǎn)足這些規(guī)格要求，提供±2,000°/sec的全格傳感范圍、< ±1%的軸間隔絕、10,000g的碰撞容忍度，以及4x5x1.2mm的包裝尺寸。ISZ-650單軸(Z)陀螺儀可補(bǔ)足IDG-650雙軸(X/Y)陀螺儀，提供將所有傳感器與其他系統(tǒng)電子組裝于同一平面的解決方案。

InvenSense功能特點(diǎn)
? 量測(cè)快速動(dòng)作的最高傳感范圍可達(dá)±2,000°/sec的全格傳感范圍(full scale range)
? 每軸皆具兩個(gè)獨(dú)立的輸出端，各自提供標(biāo)準(zhǔn)與高感應(yīng)傳感輸出，可使用較低分辨率之類(lèi)比數(shù)位轉(zhuǎn)換器(analog-to-digital convertors，ADC)來(lái)降低系統(tǒng)成本。
? IDG-650之特性為整合于單一芯片之同平面設(shè)計(jì)，擁有卓越的X/Y軸間校準(zhǔn)(cross-axis alignment)。ISZ-650單軸(Z)陀螺儀可補(bǔ)足IDG-650雙軸(X/Y)陀螺儀，提供所有傳感器與其他系統(tǒng)電子組裝于同一平面的三軸陀螺儀解決方案。
? 特殊的芯片設(shè)計(jì)與制程，達(dá)成良好抖動(dòng)排除效果
? 10,000g之最高碰撞容忍度
? 自動(dòng)歸零設(shè)定功能(auto-zero function)降低偏壓飄移(bias drift)
? 大小為4x5x1.2mm之世界最小尺寸雙軸陀螺儀
? Nasiri-Fabrication 制程平臺(tái)之設(shè)計(jì)優(yōu)勢(shì)，包含尺寸、效能與成本，是其他制程無(wú)法相比的
