Control Functions
BUF
In the case of a control function, the MSB (Bit 15) is a 1. This is
followed by two control bits, which determine the mode. There
are four different control modes: reference and gain mode, LDAC
mode, power-down mode, and reset mode. The write sequences
for these modes are shown in
.
This controls whether the reference of a group of DACs is
buffered or unbuffered. The reference of the first group of DACs
(A, B, C, and D) is controlled by setting Bit 2, and the second
group of DACs (E, F, G, and H) is controlled by setting Bit 3.
0: unbuffered reference.
1: buffered reference.
Reference and Gain Mode
GAIN
This mode determines whether the reference for each group of
DACs is buffered, unbuffered, or from VDD. It also determines
the gain of the output amplifier. To set up the reference of both
groups, set the control bits to (00), set the GAIN bits, the BUF
bits, and the VDD bits.
The gain of the DACs is controlled by setting Bit 4 for the first
group of DACs (A, B, C, and D) and Bit 5 for the second group
of DACs (E, F, G, and H).
0: output range of 0 V to VREF.
1: output range of 0 V to 2 VREF.

LDAC mode controls LDAC, which determines when data is
transferred from the input registers to the DAC registers. There
are three options when updating the DAC registers, as shown in
.

LDAC Low (00): This option sets LDAC permanently low,
allowing the DAC registers to be updated continuously.
VDD
These bits are set when VDD is to be used as a reference. The
first group of DACs (A, B, C, and D) can be set up to use VDD by
setting Bit 0, and the second group of DACs (E, F, G, and H) by
setting Bit 1. The VDD bits have priority over the BUF bits.
LDAC High (01): This option sets LDAC permanently high.
The DAC registers are latched and the input registers can
change without affecting the contents of the DAC registers.
This is the default option for this mode.
When VDD is used as the reference, it is always unbuffered and
has an output range of 0 V to VREF regardless of the state of the
GAIN and BUF bits.
LDAC Single Update (10): This option causes a single pulse on
LDAC, updating the DAC registers once.
Reserved (11): reserved.
