APPLICATION INFORMATION
Fig.15 Application diagram.
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. Eventually, the
reference ladder voltages can be derived from a well regulated V
DDA
supply through a resistor bridge and a decoupled capacitor.
