Designing of electronic circuit to measure magnetic fields from a computer

We are a university research team at the University of New South Wales requiring an electronic circuit for a magnetic field sensing application. Deliverables of the project are: - Design the entire electronic circuit needed to operate 4 x AFF756 magnetic sensors from a computer via USB. - The design needs to be coordinated with our team to ensure it will fulfil our needs - Deliver a circuit diagram for the entire circuit that can then also be used at a later stage for designing the PCB - Bill of materials Note 1: A schematic is provided to initiate the discussion and facilitate the process. Note 2: The required schematic to drive the flip coil can be found no the AFF755B datasheet.
