3.1. Description

The DMB_MLX90316 consists into a Printed Circuit Board (PCB), Magnetic Knob and a digital voltmeter

(DVM).

• The PCB implements the same application diagram as the EVB_MLX90316DC. The PCB also features

an aluminum ring in order to center the magnetic knob (see below) above the sensitive area of

MLX90316.The part is programmed to get a 1 V … 4.6 V output swing for 0 … 360 Degrees travel (i.e.

10 mV/Degree). This 3.6 V span is then further measured by the DVM (see below) after a resistive

divider 1 ÷ 10 (final sensitivity = 1 mV/Degree).

• The magnetic knob features a small SmCo magnet diametrally magnetized D6H2.5 (Diameter = 6 mm

and Height = 2.5 mm).

• The digital voltmeter: measures 10% (resistive divider 1 ÷ 10) of the output voltage and displays the

value. The reading is in mV or in Degree given the sensitivity of 1 mV/Degree.
