To ensure good device-to-device performance matching in

a system that contains multiple AD7607 devices, a symmetrical

layout between the devices is important.

Figure 54 shows a layout with two AD7607 devices. The AVCC

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

track runs to the left of the two AD7607 devices. The reference

chip is positioned between the two AD7607 devices, and the

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

Pin 42 of U2. A solid ground plane is used. These symmetrical

layout principles can also be applied to a system that contains

more than two AD7607 devices. The AD7607 devices can be

placed in a north-south direction with the reference voltage

located midway between the AD7607 devices and the reference

track running in the north-south direction, similar to Figure 54.
