Position Sensing Interface Solutions

Analog Devices Inc. Position Sensing Interface Solutions are designed for closed-loop mechanical control systems across a wide range of industries including automotive, industrial automation, process control, and military and aerospace. These sensors can measure the position of various mechanical systems. Some of these measurements include the position of the robot arm, angular position of electric motor shaft, linear displacement of a hydraulic valve, and position of aircraft flight control surfaces.

Magnetic Position Sensing Solutions

Analog Devices Inc. Magnetic Position Sensing Solutions are specially designed to measure magnetoresistance (MR) across an extremely high bandwidth. Magnetoresistance is the tendency of a material to change the value of its electrical resistance in an externally applied magnetic field.

ADA4571整合式AMR角度磁性感應器

Analog Devices ADA4571 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 ADA4571 includes two die within one package, an AMR sensor, and a fixed gain (G = 40 nominally) instrumentation amplifier. The ADA4571 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 (α) 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 ADA4571 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.
