The analog and digital supplies should be separated and decoupled.
The external voltage generator must be built such that a good supply voltage ripple rejection is achieved with respect to the LSB value.
(1) VRB and VRT are decoupled to AGND.
(2) Pin 5 should be connected to AGND; pins 3 and 10 to DGND in order to prevent noise influence.
