The ADA4571 is a high-precision 180° angle sensor with an integrated AMR angle sensor and signal conditioner. It features a maximum angular error of 0.5°, analog sine and cosine outputs, ratiometric output voltages, low thermal and lifetime drift, SAR or Σ-∆ analog-to-digital converter (ADC) drive capability, etc.
The ADA4571 is an anisotropic magnetoresistive (AMR) sensor with integrated signal conditioning amplifiers and ADC drivers. It produces two analog outputs indicating the angular position of a surrounding magnetic field within a 180° range. The device is available in an 8-lead SOIC package and is qualified for automotive applications, operating over a temperature range of −40°C to +150°C.
