AS5115 PB

AS5115 Programmable 360 Magnetic Angle Encoder with Buffered Sine and Cosine Output Signals The AS5115 is a contactless rotary encoder sensor for accurate General Description angular measurement over a full turn of 360 and over an extended ambient temperature range of -40C to 150C. Based on an integrated Hall element array, the angular position of a simple two-pole magnet is translated into analog output voltages. The angle information is provided by means of buffered sine and cosine voltages. This approach gives maximum flexibility in system design, as it can be directly integrated into existing architectures and optimized for various applications in terms of speed and accuracy. An SSI Interface is implemented for signal path configuration as well as a one time programmable register block (OTP), which allows the customer to adjust the signal path gain to adjust for different mechanical constraints and magnetic field.
