RANGE REGISTER
The range register is used to select one analog input range per analog input channel and to set the ranges for Channel 0 and Channel 1. It
is a 6-bit, write-only register with two dedicated range bits for each of the analog input channels, Channel 0 and Channel 1. There are four
analog input ranges, ±10 V, ±5 V, ±2.5 V, and 0 V to +10 V. A write to the range register is selected by setting the write bit to 1, the ZERO
bit to 0, and the register select bit to 1. After the initial write to the range register occurs, each time an analog input is selected, the
AD7321 automatically configures the analog input to the appropriate range, as indicated by the range register. The ±10 V input range is
selected by default on each analog input channel (see Table 13).
