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.
