APPLICATION INFORMATION
data format
The TLV5633 writes data either to one of the DAC holding latches or to the control register depending on the
address bits A1 and A0.

External
If an external reference voltage is applied to the REF pin, external reference must be selected.
layout considerations
To achieve the best performance, it is recommended to have separate power planes for GND, AV
DD
, and DV
DD
.
Figure 13 shows how to lay out the power planes for the TLV5633. As a general rule, digital and analog signals
should be separated as wide as possible. To avoid crosstalk, analog and digital traces must not be routed in
parallel. The two positive power planes ( AV
DD
and DV
DD
) should be connected together at one point with a
ferrite bead.
A 100-nF ceramic low series inductance capacitor between DV
DD
and GND and a 1-
μ
F tantalum capacitor
between AV
DD
and GND placed as close as possible to the supply pins are recommended for optimal
performance.
