Position Sense ADA4570 Anisotropic Magnetoresistive (AMR) Sensor

Описание: https://www.analog.com/en/technical-a... 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 output pairs that indicate the angular position of the surrounding magnetic field.
The EVAL-ADA4570SDZ evaluation board features the ADA4570 in an end of shaft magnet configuration.
The evaluation kit is composed of the EVAL-ADA4570SDZ and a magnetic stimulus on a printed circuit board (PCB) mount. To interface to a computer, the EVAL-SDP-CS1Z (SDP-S) or the EVALSDP-CB1Z (SDP-B) is required which must be ordered separately.
An illustration of the ADA4570 evaluation system consisting of the PC graphic user interface (GUI), the SDP, and the EVAL-ADA4570SDZ is shown in Figure 1 of the user guide. In the user guide, SDP refers to either the SDP-S or the SDP-B interface card. The EVAL-ADA4570SDZ allows a detailed evaluation of the ADA4570 where the software GUI demonstrates angular measurement and performs system level calibration.
The EVAL-ADA4570SDZ also provides access via a standard header for power and digital signals to the on-board ADC interface (AD7266), which allows evaluation of the ADA4570 with a user preferred microcontroller platform and to start the system software development. Users can also access the analog output signals of the ADA4570 to a user preferred ADC with a microcontroller platform.
The PCB is designed so that the sensor board can be detached from the SDP interface to provide a smaller form factor. Power supplies can be sourced from either the USB port via the SDP card or an external bench supply.
