Rev. I | Page 31 of 44
DATA REGISTER
The data register is addressed by setting the address word of the input shift register to 0x01. The data to be written to the data register is
entered in the D15 to D4 positions for the AD5412 and the D15 to D0 positions for the AD5422, as shown in Table 12 and Table 13.

Description
CLRSEL
See Table 21 for a description of the CLRSEL operation.
OVRRNG
Setting this bit increases the voltage output range by 10% (see the AD5412/AD5422 Features section).
REXT
Setting this bit selects the external current setting resistor (see the AD5412/AD5422 Features section). When
using an external current setting resistor, it is recommended to only set REXT when also setting the OUTEN
bit. Alternately, REXT can be set before the OUTEN bit is set, but the range (see Table 16) must be changed
on the write in which the output is enabled. See Figure 69 for best practice.
OUTEN
Output enable. This bit must be set to enable the outputs. The range bits select which output is functional.
SR clock
Digital slew rate control (see the AD5412/AD5422 Features section).
SR step
Digital slew rate control (see the AD5412/AD5422 Features section).
SREN
Digital slew rate control enable.
DCEN
Daisy chain enable.
