WRITE
The value written to this bit of the Control Register determines whether or not the following 11 bits will be
loaded to the Control Register. If this bit is a 1, the following 11 bits will be written to the Control Register; if it is a
0, the remaining 11 bits are not loaded to the Control Register, and it remains unchanged.
The SEQ bit in the Control Register is used in conjunction with the SHADOW bit to control the use of the
sequencer function and access the SHADOW Register. (See Table IV.)

These three address bits are loaded at the end of the present conversion sequence and select which analog
input channel is to be converted in the next serial transfer, or they may select the final channel in a consecutive
sequence as described in Table IV. The selected input channel is decoded as shown in Table II. The
address bits corresponding to the conversion result are also output on DOUT prior to the 12 bits of data,
see the Serial Interface section. The next channel to be converted on will be selected by the mux on the
14th SCLK falling edge.
Power Management Bits. These two bits decode the mode of operation of the AD7908/AD7918/AD7928
as shown in Table III.
The SHADOW bit in the Control Register is used in conjunction with the SEQ bit to control the use of the
sequencer function and access the SHADOW Register. (See Table IV.)

RANGE
This bit selects the analog input range to be used on the AD7908/AD7918/AD7928. If it is set to 0, the
analog input range will extend from 0 V to 2 REF
IN
. If it is set to 1, the analog input range will extend from
0 V to REF
IN
(for the next conversion). For 0 V to 2 REF
IN
, AV
DD
= 4.75 V to 5.25 V.
This bit selects the type of output coding the AD7908/AD7918/AD7928 will use for the conversion result.
If this bit is set to 0, the output coding for the part will be twos complement. If this bit is set to 1, the output
coding from the part will be straight binary (for the next conversion).

CODING
CONTROL REGISTER
The Control Register on the AD7908/AD7918/AD7928 is a 12-bit, write-only register. Data is loaded from the DIN pin of the
AD7908/AD7918/AD7928 on the falling edge of SCLK. The data is transferred on the DIN line at the same time that the conver-
sion result is read from the part. The data transferred on the DIN line corresponds to the AD7908/AD7918/AD7928 configuration
for the next conversion. This requires 16 serial clocks for every data transfer. Only the information provided on the first 12 falling
clock edges (after
CS
falling edge) is loaded to the Control Register. MSB denotes the first bit in the data stream. The bit functions
are outlined in Table I.
