Avago公司的 AEAT-6600-T16是业界最高分辨率的霍耳磁性编码器,包括霍耳元件,模拟前端和数字信号处理,具有10-16位的分辨率,可精密测量360度旋转的角度.器件的工作电压5V或3.3V,3线或2线SSI接口模式的绝对值输出,增量ABI或UVW以及PWM输出模式,用户可编程的零位置,指向和标志脉宽,主要用在工业自动化和机器人,替代分解器和电位计,无刷DC马达的三相换向等.本文介绍了AEAT-6600-T16主要特性和指标, OTP可编模式电路图, 对准模式电路图, PCB级应用电路图以及HEDS-8937编程器主要特性等.

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.
