AD7607
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 AV
supply plane runs to the right of both devices. The V
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.
