ADI ADA4570 Integrated AMR Angle Sensor and Signal Conditioner
The ADA4570 is an anisotropic magnetoresistive (AMR) sensor with integrated signal conditioning amplifiers and analog-to-digital converter (ADC) drivers. The ADA4570 produces two differential 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. The ADA4570 delivers amplified differential cosine and sine output signals, with respect to the angle, when the magnetic field is rotating in the x-axis and the y-axis (x-y) plane. The output voltage range is ratiometric to the supply voltage.
