separate ground plane, but separating the lines helps). It is
essential to minimize noise on the REFIN line because it
couples through to the DAC output.
Avoid crossover of digital and analog signals. Traces on
opposite sides of the board should run at right angles to each
other. This reduces the effects of feedthrough on the board. A
microstrip technique is by far the best but not always possible
with a double-sided board. In this technique, the component
side of the board is dedicated to ground plane, whereas signal
traces are placed on the solder side.
Layout—DC-to-DC Converters
To achieve high efficiency, good regulation, and stability, a well-
designed printed circuit board layout is required.
Follow these guidelines when designing printed circuit boards
Keep the low ESR input capacitor, CIN, close to AVCC and
PGND.
Keep the high current path from CIN through the inductor,
LDCDC, to SWX and PGND as short as possible.
Keep the high current path from CIN through LDCDC, the
rectifier, DDCDC, and the output capacitor, CDCDC, as short as
possible.
Keep high current traces as short and as wide as possible.
The path from CIN through the inductor, LDCDC, to SWX and
PGND should be able to handle a minimum of 1 A.
Place the compensation components as close as possible to
COMPDCDC_x.
Avoid routing high impedance traces near any node
connected to SWx or near the inductor to prevent radiated
noise injection.
GALVANICALLY ISOLATED INTERFACE
In many process control applications, it is necessary to provide
an isolation barrier between the controller and the unit being
controlled to protect and isolate the controlling circuitry from
any hazardous common-mode voltages that may occur. The
Analog Devices iCoupler products can provide voltage isolation
in excess of 2.5 kV. The serial loading structure of the AD5755
makes it ideal for isolated interfaces because the number of
interface lines is kept to a minimum. Figure 86 shows a 4-
channel isolated interface to the AD5755 using an ADuM1400.
