AS5145B

General Description Figure 1: Added Value of Using AS5145 Benefits Highest reliability and durability Simple programming Multiple interfaces Ideal for motor applications Failure diagnostics Easy setup AS5145H/AS5145A/ AS5145B 12-Bit Programmable Magnetic Rotary Encoder The AS5145 is a contactless 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 can be placed above or below the IC. The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 0.0879º = 4096 positions per revolution. 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.
