GENERAL DESCRIPTION
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.
FEATURES
► Contactless angular measurement
► High precision 180° angle sensor
► Typical angular error of ±0.1°
► Low output noise of 850 μV rms
► Sine and cosine differential outputs
► Ratiometric analog voltage outputs
► Negligible hysteresis
► SAR or Σ-Δ ADC compatible
► Temperature compensated AMR bridge
► Industrial temperature range: −40°C to +125°C
► Automotive temperature range: −40°C to +150°C
► EMI resistant
► Fault diagnostics
► VDD from 2.7 V to 5.5 V
► Minimal phase error of 0.85° at 30,000 rpm
► AEC-Q100 qualified for automotive applications
► Single chip solution
► Available in an 8-lead SOIC package
APPLICATIONS
► 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
