• Manufacturer Part Number: MAX522
• Description: Dual / 8-Bit / Voltage-Output Serial DAC in 8-Pin SO Package
• Manufacturer: Maxim

______________
The MAX522 is specified for single-supply operation
with V
monly used supply voltages in 3V and 5V systems.
There is no internal power-on reset. Therefore, at
power-up, perform an initial write operation to set the
outputs to the desired voltage.
GND should be connected to the highest quality
ground available. Bypass V
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 0.1µF to 4.7µF 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.
