Product Overview
ADA4571WHRZ-R7 is an integrated AMR angle sensor and signal conditioner. It is an anisotropic magneto resistive (AMR) sensor with integrated signal conditioning amplifiers and ADC drivers. It produces two 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 (G = 40 nominally) instrumentation amplifier. It delivers clean and amplified cosine and sine output signals related to the angle of a rotating magnetic field. 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 applications 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.
- Analog sine and cosine outputs, ratiometric output voltages, qualified for automotive application
- Low thermal and lifetime drift, SAR or Σ-∆ analogue-to-digital converter (ADC) drive capable
- Magneto resistive (MR) bridge temperature compensation mode, EMI resistant
- Fault diagnostics, VDD from 2.7V to 5.5V, minimum phase delay
- Output noise is 500µV rms typical at (-40°C ≤ TA ≤ +150°C, VDD = 2.7V to 5.5V)
- Output -3dB cut-off frequency is 100KHz typical at (amplifier BW, CL = 10pF)
- Power supply rejection ratio is 80dB typical at (-40°C ≤ TA ≤ +150°C, VDD = 2.7V to 5.5V)
- Quiescent supply current is 4.5mA typical at (-40°C ≤ TA ≤ +150°C, VDD = 2.7V to 5.5V)
- Delay time is 2µs typical at (rotation frequency = 30,000rpm)
- Operating temperature range from -40°C to +150°C, 8-lead SOIC-N package
