12. Application information
ADC0804S030_040_050_2
Product data sheet
Fig 14. Application diagram
(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.
The analog and digital supplies should be separated and well decoupled
A user manual is available that describes the demonstration board that uses the version ADC0804S030/040/050/ family with an
application environment.
