AD8110/AD8111
The three power supply pins AVCC, DVCC, and AVEE should
be connected to good quality, low noise, ± 5 V supplies. Where
the same ± 5 V power supplies are used for analog and digital,
separate cables should be run for the power supply to the evalu-
ation board’s analog and digital power supply pins.
As a general rule, each power supply pin (or group of adjacent
power supply pins) should be locally decoupled with a 0.01 µF
capacitor. If there is a space constraint, it is more important to
decouple analog power supply pins before digital power supply
pins. A 0.1 µF capacitor, located reasonably close to the pins,
can be used to decouple a number of power supply pins. Finally
a 10 µF capacitor should be used to decouple power supplies as
they come on to the board.
Controlling the Evaluation Board from a PC
The evaluation board includes Windows-based control software
and a custom cable that connects the board’s digital interface to
the printer port of the PC. The wiring of this cable is shown in
Figure 15. The software requires Windows 3.1 or later to oper-
ate. To install the software, insert the disk labeled “Disk #1 of
2'' in the PC and run the file called SETUP.EXE. Additional
installation instructions will be given on-screen. Before begin-
ning installation, it is important to terminate any other Windows
applications that are running.
When you launch the crosspoint control software, you will be
asked to select the printer port you are using. Most modern PCs
have only one printer port, usually called LPT1. However some
laptop computers use the PRN port.
