11. Application Information

The MLX90819 only needs 2 capacitors in the application, a 47nF decoupling capacitor on the supply line and a 47nF load on

the analog output pin. When the SENT output is used a 2.2nF capacitor is recommended. Consult Melexis to discuss the ideal

application schematics depending on the EMC specs to be fulfilled.
