Product Overview

ADA4571-2 is a 2-channel anisotropic magneto resistive (AMR) sensor with integrated signal conditioning amplifiers and ADC drivers. The device produces analogue outputs that indicate the angular position of the surrounding magnetic field. Each channel consists of two die within one package: an AMR sensor and a variable gain instrumentation amplifier. The ADA4571-2 delivers clean and amplified cosine and sine output signals per channel related to the angle of a rotating magnetic field. The output voltage range is ratiometric to the supply voltage. Each sensing channel contains two separated wheatstone bridges at a relative angle of 45° to one another. Application includes permanent magnet synchronous motor (PMSM) control and positioning, contactless angular measurement and detection, magnetic angular position sensing.
  • High precision, 2-channel, isolated AMR angle sensor for redundant systems
  • Angular range of 0° to 180°, typical angular error of 0.1°
  • Analog sine and cosine outputs per channel
  • Ratiometric output voltages, low thermal and lifetime drift
  • Successive approximation register (SAR) analogue-to-digital converter (ADC) or Σ-Δ ADC drive capable
  • Magnetoresistive (MR) bridge temperature compensation mode
  • Supply voltage (VDD) from 3V to 5.5V
  • Minimum phase delay, qualified for automotive applications
  • Angle measurement range from 0 to 180Degrees (-40°C <= TA <= +150°C, VDD = 3V)
  • 16 lead SOIC-N package, operating temperature range from -40°C to +150°C
