Notes:
For proper operation a 100nF or bigger bypass capacitor C1 should be placed as close as possible to the VDD and GND
pins of MLX90290.
For embedded applications the components R_S, R_L and C_L are not required.

Notes:
For proper operation a 100nF or bigger bypass capacitor C1 should be placed as close as possible to the VDD and GND
pins of MLX90290. For harsh and noisy environment, a bypass capacitor C2 of 1nF to 10nF can be placed on the output.
For improved EMC performance an additional resistance, Rs and capacitors, C3 and C4 placed close to the connector of
the module are recommended. Recommended values for: Rs ≥ 50E, 1nF ≥ C3 ≤ 4.7nF, 1nF ≥ C4 ≤ 10nF.
For embedded applications the components R_L and C_L are not required.
