AS5145磁性旋轉(zhuǎn)編碼器 IC 是一款非接觸式的完整系統(tǒng)級(jí)芯片，可在一圈 360° 范圍內(nèi)提供分辨率達(dá) 0.0879° 的角度測量，即每轉(zhuǎn) 4, 096 個(gè)位置。使用一個(gè)簡單的串行接口或 PMW 信號(hào)即可讀取該數(shù)字角度數(shù)據(jù)。另外，該器件采用改進(jìn)的插值算法，可實(shí)現(xiàn)增量正交輸出模式，并能性編程為 10 位至 12 位分辨率。由于具有更佳的噪聲特性，進(jìn)一步得到提升。

除了支持用戶化零位編程、芯片 ID 和幫助磁鐵正確定位的診斷功能等奧地利微電子編碼器系列的所有標(biāo)準(zhǔn)功能外，AS5145 還能提供一種與外部電路同步的特殊功能，以及正弦/余弦數(shù)字輸出模式。當(dāng)該模式激活時(shí)，將輸出 16 位正弦和 16 位余弦雙通道數(shù)字?jǐn)?shù)據(jù)，并在外部進(jìn)行計(jì)算。

Description

The AS5145 is a contactless magnetic rotary encoder for accurate angular measurement over a full turn of 360°. It is a system-on-chip, combining integrated Hall elements, analog front end and digital signal processing in a single device. To measure the angle, only a simple 2-pole magnet, rotating over the center of the chip, is required. The magnet may be placed above or below the IC. The absolute angle measurement provides instant indication of the magnet's angular position with a resolution of 0.0879° = 4096 postitions per revoloution. This digital data is available as a serial bit stream and as a PWM signal. An internal voltage regulator allows the AS5145 to operate at either 3.3V or 5V supplies.
