Function
All operations to other registers are initiated through
the Communications register. This controls whether
subsequent operations are read or write operations
and also selects the register for that subsequent
operation.
Provides status information on conversions, cali-
brations, error conditions, and the validity of the
reference voltage.
Controls functions such as mode of operation, channel
configuration, and oscillator operation in power-down.
This register is used to enable the main ADC and to
configure the main ADC for range, channel selection,
16-/24-bit operation, and unipolar or bipolar operation.
This register is used to enable the aux ADC and to
configure the Aux ADC for range, channel selection,
unipolar or bipolar operation, and input range.
This register is used to control and configure the
various excitation and burnout current source options
available on-chip along with controlling the I/O port.
This register determines the amount of averaging
performed by the sinc filter and consequently deter-
mines the data update rate of the AD7719. The filter
register determines the update rate for both the main
and aux ADCs.
