ADI ADA4571BRZ

角度磁阻180°（±90°），连续模拟电压2.7V ~ 5.5V

Overview

Analog Devices ADA4571BRZ consists of anisotropic magnetoresistive (AMR) sensors with integrated signal conditioning amplifiers and ADC drivers.  ADA4571's two analog outputs indicate the angular position of the surrounding magnetic field. The ADA4571BRZ includes two die within one package, an AMR sensor, and a fixed gain (G = 40 nominally) instrumentation amplifier. The ADA4571BRZ provides clean and amplified cosine and sine output signals related to the angle of a rotating magnetic field. The output voltage range is ratiometric to the supply voltage. The sensor contains two Wheatstone bridges, at a relative angle of 45� to one another. A rotating magnetic field in the x-y sensor plane delivers two sinusoidal output signals with the double frequency of the angle () between sensor and magnetic field direction. Within a homogeneous field in the x-y plane, the output signals are independent of the physical placement in the z direction (air gap). Available in an 8-lead SOIC package, the ADA4571BRZ Integrated AMR Angle Magnetic Sensors & Signal Conditioner is ideal for absolute position measurement (linear and angle), brushless dc motor control and positioning, actuator control and positioning, contactless angular measurement and detection, and magnetic angular position sensing.
