Figure 18. Flowchart for Setting Up and Reading from the AD7705
CONFIGURING THE AD7705/AD7706
The AD7705/AD7706 contains six on-chip registers that the
user can accesses via the serial interface. Communication with
any of these registers is initiated by writing to the Communica-
tions Register first. Figure 18 outlines a flow diagram of the
sequence used to configure all registers after a power-up or reset
on the AD7705, similar procedures apply to the AD7706. The
flowchart also shows two different read options—the first where
the
DRDY
pin is polled to determine when an update of the
data register has taken place, the second where the
DRDY
bit of
the Communications Register is interrogated to see if a data
register update has taken place. Also included in the flowing dia-
gram is a series of words that should be written to the registers
for a particular set of operating conditions. These conditions
are gain of one, no filter sync, bipolar mode, buffer off, clock of
4.9512MHz and an output rate of 50 Hz.
