Evaluation Board (EVB MLX90316DC) 1.1. Description The EVB MLX90316DC consists into a Printed Circuit Board (PCB) and Magnetic Knob. The PCB implements the recommended application diagram from the MLX90316 datasheet. The MLX90316DC (SOIC-8) is mounted on the board. It also includes an aluminum ring in order to center the magnetic knob (see below) above the sensitive area of MLX90316. By default, the output transfer characteristic is programmed to get a 10%Vdd ... 90%Vdd analog output swing for 0 360 Degrees travel (complete revolution). The magnetic knob features a small SmCo magnet diametrally magnetized D6H2.5 (Diameter = 6 mm and Height = 2.5 mm). 1.2. Application Diagram The Pin SCLK and /SS are left floating in order to enable the use of the EVB in Serial Protocol mode. If this mode is not activated, we recommend shorting those pins to GND through 0 Ohm resistor. It is mandatory to run EMI test. If the Serial Protocol mode is activated, the PCB allows the introduction of decoupling capacitor. 39xx9031601 Page 1 of 6 Apr. 06 Rev 001 8 5 1 4 MLX90316 Evaluation Board Demonstration Board VDD C1 100nF GND Vdd Vss MLX90316 C2 Test 1 Vdig 100nF C3 100nF /SS Test 2 OUT Out SCLK MISO/MOSI SCLK /SS 1.3.
