DG1208, DG1209 Evaluation Kits
General Description
The DG1208/DG1209 evaluation kits (EV kits) provide a proven design to evaluate the DG1208/DG1209,
low-leakage and low-charge-injection multiplexer devices. The DG1208EVKIT# and DG1209EVKIT# are fully
assembled and tested, and come populated with the
DG1208EUE+ and DG1209EUE+ multiplexers, respectively. 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.

DG1208EVKIT# Quick Start
Recommended Equipment
●●
DG1208EVKIT#
●●
±20V, 100mA tri-output DC power supply
●●
Digital multimeter
Procedure
The DG1208EVKIT# is fully assembled and tested.
Follow the steps below to verify board operation:
1) Connect the tri-output power supply to the
DG1208EVKIT#:
●● Set the positive voltage supply to +15V and connect to the VPOS test point.
●● Set the negative voltage supply to -15V and connect to the VNEG test point.
2) Verify that all jumpers are in their default positions as
shown in Table 1.
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).
8) Repeat steps 6 and 7 to test all 8 channels. Verify
the on-resistance of each channel is 100Ω (typ). Use
the relations in Table 2 to set the jumpers at A2–A0
selection inputs.
●● Connect the return of the power supply to GND
test point.

Detailed Description
Configure the DG1208/DG1209 EV Kits
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 associated with them.
Table 5. DG1208 EV Kit Test Points
TEST POINTS
DESCRIPTION
COM
COM output channel
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 channels share an SMA connector. See Table 1 and Table 3
for the shunt positions to connect SMA to correct analog
channels.
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 switching 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.
