Layout Considerations
Digital and AC transient signals coupling to GND can
create noise at the output. Use proper grounding tech-
niques, such as a multilayer board with a low-inductance
ground plane. Wire-wrapped boards and sockets are not
recommended. For optimum system performance, use
printed circuit (PC) boards. Good PC board ground lay-
out minimizes crosstalk between DAC outputs, reference
inputs, and digital inputs. Reduce crosstalk by keeping
analog lines away from digital lines.
