To ensure good device-to-device performance matching, in a

system that contains multiple AD7608 devices, a symmetrical

layout between the AD7608 devices is important.

Figure 61 shows a layout with two devices. The AVCC supply

plane runs to the right of both devices. The VDRIVE supply

track runs to the left of the two devices. The reference chip

is positioned between both the two devices and the reference

voltage track runs north to Pin 42 of U1 and south to Pin 42

to U2. A solid ground plane is used.

These symmetrical layout principles can be applied to a system

that contains more than two AD7608 devices. The AD7608

devices can be placed in a north-south direction with the reference

voltage located midway between the AD7608 devices with the

reference track running in the north-south direction similar to

Figure 61.
