• Manufacturer Part Number: MAX5722AUA
• Description: 12-Bit, Low-Power, Dual, Voltage-Output DAC with Serial Interface
• Manufacturer: MAXIM [Maxim Integrated Products]

Careful PC board layout is important for optimal system
performance. To reduce noise injection and digital feed-
through and keep analog and digital signals separate.
Ensure that that the return path from GND to the supply
ground is short and low impedance. Use a ground
plane. Bypass V
close as possible to V
