APPLICATION INFORMATION
Fig.12 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. The reference
ladder voltages can also be derived from a well regulated VDDA supply through a resistor bridge and a decoupled capacitor.
For applications where the input signal must remain well centred around middle scale, VRM must be decoupled and connected to analog input signal
(pin 5) through a resistor. The values must be defined in accordance with the input signal frequency in order to avoid direct coupling into the ADC ladder
(e.g. R = 5 k
and C = 100 nF).
(1) VRB, VRM and VRT are decoupled to VSSA.
(2) Pin 11 should be connected to VSSA in order to prevent noise influence.
