ADI Analog Devices ADA4571-2WHRZ-RL Board Mount Hall Effect/Magnetic Sensor

Analog Devices' ADA4571 is an anisotropic magnetoresistive (AMR) sensor that integrates a signal conditioning amplifier and ADC driver. The ADA4571 produces two analog outputs that indicate the angular position of the surrounding magnetic field. The ADA4571 integrates two chips,an AMR sensor and a fixed gain (nominal G = 40) instrumentation amplifier in a single package. The ADA4571 provides clean,amplified cosine and sine output signals related to the of a rotating magnetic field. The output voltage range is proportional to the supply voltage. The sensor consists of two Wheatstone bridges at of 45° to each other. The rotating magnetic field in the x-y sensor plane provides two sinusoidal output signals,and the (α) between the sensor and the direction of the magnetic field doubles the frequency. Within a uniform field in the x-y plane,the output signal is independent of the physical position of the z-axis (air gap). ADA4571 Integrated AMR Magnetic Sensor & Signal Conditioner in 8-pin SOIC package,suitable for absolute position measurement (linear and angular),brushless DC motor control and positioning,actuator control and positioning,non-contact measurement and Detection,magnetic position detection.
