ADA4571BRZ

ADA4571 is an anisotropic magneto resistive (AMR) sensor with integrated signal conditioning amplifiers and ADC drivers. It produces two analog outputs that indicate the angular position of the surrounding magnetic field. It consists of two die within one package, an AMR sensor, and a fixed gain (G = 40 nominally) instrumentation amplifier. It delivers clean and amplified cosine and sine output signals related to the angle of a rotating magnetic field. The output voltage range is ratio metric to the supply voltage. It is used in application such as absolute position measurement (linear and angle), brushless dc motor control and positioning, actuator control and positioning, contactless angular measurement and detection, magnetic angular position sensing etc.
