Applications Information
Power Supplies
A single +12V to +15V supply is required to realize a
0 to 10V output swing. A dual ±12V to ±15V supply is
required to realize a ±10V output swing, and allows
unipolar, 0 to +10V output if UNI/
BIP
is forced high. A
+3V to +5V digital power supply and a +2.000V to
+5.250V external reference voltage are also required.
Always bring up the reference voltage last. The other
power supplies do not require sequencing.
Power-Supply Bypassing and Ground
Management
Bypass V
DD
and V
SS
with 0.1μF and 1.0μF capacitors to
AGND, and bypass V
CC
with 0.1μF and 1.0μF capacitors
to DGND. Minimize trace lengths to reduce inductance.
Digital and AC transient signals on AGND or DGND can
create noise at the output. Connect AGND and DGND to
the highest quality ground available. Use proper ground-
ing techniques, such as a multilayer board with a low-
inductance ground plane or star connect all ground-
return paths back to AGND. Carefully lay out the traces
between channels to reduce AC crosscoupling and
crosstalk. Wire-wrapped boards, sockets, and bread-
boards are not recommended.
