APPLICATION INFORMATION
Fig.16 Application diagram.
The analog and digital supplies should be separated and decoupled.
The external voltage regulator 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 VCCA supply through a resistor bridge and a decoupled capacitor.
(1) VRB, VRM and VRT are decoupled to AGND.
(2) Pins 15 and 16 may be connected to DGND in order to prevent noise influence.
