Features and Benefits

  • Full featured evaluation board for the ADA4570
  • PC control in conjunction with the System Demonstration Platform (SDP) (EVAL-SDP-CS1Z, SDP-S or EVAL-SDP-CB1Z, SDP-B)
  • PC software for data measurement and display

Product Details

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.

For full details, see the ADA4570 data sheet, which must be used in conjunction with the user guide when using the EVAL-ADA4570SDZ.
