AD7329
SEQUENCE REGISTER
The sequence register on the AD7329 is an 8-bit, write-only register. Each of the eight analog input channels has one corresponding bit in
the sequence register. To select a channel for inclusion in the sequence, set the corresponding channel bit to 1 in the sequence register.

RANGE REGISTERS
The range registers are used to select one analog input range per analog input channel. Range Register 1 is used to set the ranges for
Channel 0 to Channel 3. It is an 8-bit, write-only register with two dedicated range bits for each of the analog input channels from
Channel 0 to Channel 3. There are four analog input ranges, ±10 V, ±5 V, ±2.5 V, and 0 V to +10 V. A write to Range Register 1 is selected
by setting the write bit to 1 and the range select bits to 0 and 1. After the initial write to Range Register 1 occurs, each time an analog
input is selected, the AD7329 automatically configures the analog input to the appropriate range, as indicated by Range Register 1.
The ±10 V input range is selected by default on each analog input channel (see Table 15).

Range Register 2 is used to set the ranges for Channel 4 to Channel 7. It is an 8-bit, write-only register with two dedicated range bits for
each of the analog input channels from Channel 4 to Channel 7. There are four analog input ranges, ±10 V, ±5 V, ±2.5 V, and 0 V to +10 V.
After the initial write to Range Register 2 occurs, each time an analog input is selected, the AD7329 automatically configures the analog
input to the appropriate range, as indicated by Range Register 2. The ±10 V input range is selected by default on each analog input
channel (see Table 15).
