General Description
Features
The DG1208/DG1209 evaluation kits (EV kits) pro-
vide a proven design to evaluate the DG1208/DG1209,
low-leakage and low-charge-injection multiplexer devic-
es. The DG1208EVKIT# and DG1209EVKIT# are fully
assembled and tested, and come populated with the
DG1208EUE+ and DG1209EUE+ multiplexers, respec-
tively. The DG1208 is a single 8-to-1 multiplexing device;
the DG1209 is a dual 4-to-1 device. Both multiplexer
devices are available in 4mm x 4mm 16-lead TQFN or
16-lead TSSOP packages.

3) Turn on the power supply. Ensure that both positive
and negative supplies have less than 1mA (max).
4) Move the shunt at J15 to position 1–2 to enable the
device. Verify the voltage at the EN test point is 15V.
5) Measure the on-resistance of channel 1 between
COM and NO1 at 100Ω (typ).
6) Move the shunt at J14 from position 2–3 to position
1–2. Verify the voltage at the A0 test point is 15V.
7) Measure the on-resistance of channel 2 between
COM and NO2 at 100Ω (typ).

Configure the DG1208/DG1209 EV Kits
Detailed Description
On the DG1208/DG1209 EV kits, every analog and digital
channel has their own test points. The output channels
have dedicated SMA connectors; each four input chan-
nels share an SMA connector. See Table 1 and Table 3
for the shunt positions to connect SMA to correct analog
channels.
The DG1208 and DG1209 continue the Maxim’s family of
low-leakage and low-charge-injection multiplexers. The
DG1208/DG1209 EV kits have multiple SMA connectors,
test points, and jumpers for inputs and outputs, allowing
easy configuration and evaluation.
The DG1208/DG1209 EV kits can be powered from either
a bipolar supply or a single supply with nominal voltage up
to 20V. Digital Inputs A_ and EN can be configured high
or low using on-board jumpers, or directly from the test
points. Each analog input and output can be accessed
from the SMA connector, as well as the test point associ-
ated with them.
Use the relations in Table 5 and Table 6 to find the test
point functions when evaluating the DG1208 or DG1209.
Control Logic
The DG1208 EV kit uses three selection inputs A2, A1
and A0, and an enable input EN to determine the switch-
ing logic. The DG1209 EV kit uses two selection inputs A1
and A0, and an enable input EN. See Table 2 and Table 4
for detailed control logic.
