Method of selecting output resistance
The CXD2073Q has a built-in current output-type D/A converter. To obtain the output voltages, connect
resistors to AYO and ACO pins.
VFS = IFS
×
R
Here, VFS is output full-scale voltage, IFS is output full-scale current, and R is the output resistance
connected to each IO.
In addition, connect a resistance of 16 times the output resistor to the reference current pin IRF. In the case
where the value comes to be impractical, use a value of resistance as close to the value calculated as
possible. At that time,
VFS = VRF

R/R'.
R is the output resistance connected to each IO, R' is the resistance connected to IRF, and VRF is the VRF
pin voltage. Power consumption can be reduced by using higher resistance values, but then glitch energy
and data settling time increase contrastingly. Select optimum resistance values according to the system
applications.
In case of the circuit above, VFS = 2 [V]
