ADA4570BRZ-RL
Angular Magnetoresistive Sensor 2 Axis 8-Pin SOIC N T/R
Analog DevicesADA4570: Integrated AMR Angle Sensor and Signal Conditioner with Differential Outputs
The ADA4570 is an anisotropic magnetoresistive (AMR) sensor with integrated signal conditioning amplifiers and ADC drivers. It produces four analog outputs that indicate the angular position of the surrounding magnetic field.
The ADA4570 consists of two die within one package, an AMR sensor, and a fixed gain instrumentation amplifier. It delivers clean and amplified differential cosine and sine output signals related to the angle of a rotating magnetic field. The output voltage range is radiometric to the supply voltage.
Key Features and Benefits
• Best angular accuracy to reduce torque ripple; improves NVH, which improves motor commutation efficiency and smoothness
• Lowest phase delay enables fast closed-loop control and high dynamic applications
• Lowest noise improves reliability while reducing size and weight
Applications
• Automotive—Motor Control: Starter generator motor (SGM), electrical power steering (EPS), traction motor
• Industrial Automation: Motor control, encoder, robotics
Evaluation Board
The ADA4570 can be evaluated with the EVAL-ADA4570SDZ.
