Avago公司的 AEAT-6600-T16是業(yè)界最高分辨率的霍耳磁性編碼器,包括霍耳元件,模擬前端和數(shù)字信號處理,具有10-16位的分辨率,可精密測量360度旋轉(zhuǎn)的角度.器件的工作電壓5V或3.3V,3線或2線SSI接口模式的絕對值輸出,增量ABI或UVW以及PWM輸出模式,用戶可編程的零位置,指向和標(biāo)志脈寬,主要用在工業(yè)自動化和機器人,替代分解器和電位計,無刷DC馬達的三相換向等.本文介紹了AEAT-6600-T16主要特性和指標(biāo), OTP可編模式電路圖, 對準(zhǔn)模式電路圖, PCB級應(yīng)用電路圖以及HEDS-8937編程器主要特性等. The Avago AEAT-6600 angular magnetic encoder IC is a contact less magnetic rotary encoder for accurate angular measurement over a full turn of 360 degrees. 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 two-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 0.005° = 65 536 positions per revolution. This digital data is available as a serial bit stream and as a PWM signal. An internal voltage regulator allows the AEAT-6600 to operate at either 3.3 V or 5 V supplies.
