CONFIGURING THE AD7705/AD7706
The AD7705/AD7706 contain six on-chip registers that the user
can access via the serial interface. Communication with any of
these registers is initiated by first writing to the communication
register. Figure 21 outlines a flowchart of the sequence used to
configure registers after a power-up or reset on the AD7705;
similar procedures apply to the AD7706.
The flowchart also shows two read options—one polls the DRDY
pin, and the other interrogates the DRDY pin. In addition,
Figure 21 shows a series of words that should be written to the
registers for the following operating conditions: Gain 1, no
filter sync, bipolar mode, buffer off, clock of 4.9512 MHz, and
output rate of 50 Hz.
