Product Overview

ADA4570 is an anisotropic magneto resistive (AMR) sensor with integrated signal conditioning amplifiers and analogue-to-digital converter (ADC) driver. It produces two differential analogue outputs that indicate the angular position of the surrounding magnetic field. It consists of two die within one package, an AMR sensor, and a fixed gain instrumentation amplifier. It 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. The sensor contains two Wheatstone bridges, at a relative angle of 45° to one another. It is used in application such as absolute position measurement (linear and angle), brushless dc motor control and positioning, actuator control and positioning, contactless angular measurement and detection, magnetic angular position sensing etc.
  • Contactless angular measurement
  • High precision 180° angle sensor
  • Typical angular error of ±0.1°, supply current is 4.5mA typical
  • Low output noise of 850µV rms typical
  • Ratiometric analogue voltage outputs, negligible hysteresis
  • SAR or Σ-Δ ADC compatible, temperature compensated AMR bridge
  • EMI resistant, fault diagnostics, single chip solution
  • VDD from 2.7V to 5.5V, minimal phase error of 0.85° at 30,000rpm
  • Operating temperature is -40°C to +125°C
  • Package style is 8-lead NSOIC
