DAC Configuration Register (Read/Write)
[Address = 1Bh]
This configuration register is an 8-bit read/write register that is
used to control the output ranges of all four DACs and also to
control the loading of the DAC registers if the LDAC pin is
disabled (Bit C3 = 1, Control Configuration 3 register).

LDAC Configuration Register (Write-Only)
[Address = 1Ch]
This configuration register is an 8-bit write register that is used
to control the updating of the quad DAC outputs if the LDAC
pin is disabled and Bits D4:D5 of the DAC configuration reg-
ister are both set to 1. Also selects either the internal or external
V
ing, i.e., reading back from this register will always give 0s for
these bits.

00 = A write to any DAC register generates LDAC
command that updates that DAC only.
01 = A write to DAC B or DAC D register generates
LDAC command that updates DACs A, B or DACs C, D,
respectively.
10 = A write to DAC D register generates LDAC
command that updates all four DACs.
11 = LDAC command generated from LDAC register.
