Notes on Operation
Selecting the Output Resistance
CXD2309AQ is a current output type D/A converter. The output voltage can be obtained by connecting the
reslstor R
OUT
to the current output pins RO, GO and BO.
Specifications:
Output full-scale voltage V
FS
= 18 to 2.0 [V]
Output full-scale current I
FS
= 9.0 to 10.0 [mA]
Calculate the output resistance from V

R
OUT
. Connect a resistance sixteen times the output
resistance to the reference current output pin IREF. In some cases, as this value may not exist, a similar
value can be used instead.
Note that the V
FS
Will be the following.

V
REF
is the voltage set at the reference voltage input pin VREF, R
OUT
is the resistor to be connected to the
current output pins RO, GO, BO and R
IR
is the resistor to be connected to the IREF. Power consumption can
be reduced by increasing the resistance, but this will on the contrary increase the glitch energy and data
setting time. Set the best values according to the purpose of use.
Power supply, ground
Separate the power supply and ground of the analog and digital signals around the device to reduce noise
effects. Bypass the power supply pin to each ground with a 0.1μF ceramics capacitor as near as possible to
the pin for both the digital and analog signals.
Latch up
Analog and digital power supplies must be able to share the same power supply of the board. This is to
prevent latch up caused by potential difference between the two pins when the power is turned on. See
"Latch Up Prevention" on Page 11.
IREF
The IREF pin is very sensitive to improve the AC characteristics. Pay attention for capacitance component
not to attach to this pin because its output may become unstable.
Output full-scale voltage
For the applications using the RGB signal, the color balance may be broken up when the RO, GO and BO
output full-scale voltages are used with not adjustment.
