Applications Information
The MAX5222 is specified for single-supply operation
with VDD ranging from 2.7V to 5.5V, covering all com-
monly used supply voltages in 3V and 5V systems.
Initialization
An internal power-on reset circuit forces the outputs to
zero scale and initializes all external registers to zero.
This is equivalent to being in the shutdown state.
Therefore, at power-up, perform an initial write opera-
tion to set the outputs to the desired voltage.
Power-Supply and
Ground Management
GND should be connected to the highest quality
ground available. Bypass VDD with a 0.1F to 0.22F
capacitor to GND. The reference input can be used
without bypassing. For optimum line/load-transient
response and noise performance, bypass the refer-
ence input with 0.1F to 4.7F to GND. Careful PC
board layout minimizes crosstalk among DAC outputs,
the reference, and digital inputs. Separate analog lines
with ground traces between them. Make sure that high-
frequency digital lines are not routed in parallel to ana-
log lines.
