Single 8 bits ADC, up to 30 MHz, 40 MHz or 50 MHz

12. Application information

12.1 Alternative parts

The following alternative parts are also available:

[1]

Pin to pin compatible

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.

(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.
