• Manufacturer Part Number: MAX5548
• Description: High-Output-Current DAC
• Manufacturer: Maxim Integrated Products

Ensure that the voltage applied to REFIN does not
exceed V
not possible, connect an external Schottky diode
between REFIN and V
absolute maximum ratings.
Digital or AC transient signals on GND create noise at
the analog output. Return GND to the highest-quality
ground plane available. For extremely noisy environ-
ments, bypass REFIN and V
0.1µF capacitors with the 0.1µF capacitor as close to
the device as possible. Careful PC board ground layout
minimizes crosstalk between the DAC outputs and
digital inputs.
