The analog and digital supplies should be separated and well decoupled.

A user manual is available that describes the demonstration board that uses the ADC1003S030/040/050 family in an

application environment.

(1) RB, RM and RT are decoupled to AGND.

(2) Pin 15 may be connected to DGND in order to prevent noise influence.

(3) Decoupling capacitor for supplies: must be placed close to the device.
