DG120X Evaluation Kit
General Description
Benefits and Features
● SMA Connectors for Analog Inputs and Outputs
● Jumpers at A3-A0 and EN Digital Inputs for Easy
The DG120X evaluation kit (EV kit) provides a proven
design to evaluate the DG1206/DG1207, a low-leak-
age and low-charge-injection multiplexer device. The
DG120XEVKIT# is fully assembled and tested, and
comes populated with the DG1206EUI+, the 16-to-1
multiplexer device. Refer to the DG120X EV Kit Board
Picture.
Configuration
● Test Points for All Digital and Analog Signals
● Fully Assembled and Tested
● Proven PCB Layout
Ordering Information appears at end of data sheet.
The DG120XEVKIT# can also be used to evaluate
DG1207, the 8-to-1 device from the same multiplexer
family. See the Configure the DG120X EV Kit section for
more information.

4) Move shunt at J27 to position 1–2 to enable the de-
vice. Verify the voltage at the EN test point is 15V.
Quick Start
Recommended Equipment
● DG120XEVKIT#
5) Measure the on-resistance of channel 1 between
COMA and NO1 at 100Ω (typ).
● ±20V, 100mA tri-output DC power supply
● Digital multimeter
6) Move the shunt at J18 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
Procedure
COMA and NO2 at 100Ω (typ).
The DG120X EV kit is fully assembled and tested. Follow
the steps below to verify board operation:
8) Repeat steps 6 and 7 to test all 16 channels. Verify
the on-resistance of each channel is 100Ω (typ). Use
the relations in Table 2 to set the jumpers at A3–A0
selection inputs.
1) Connect the three-output power supply to the
DG120XEVKIT#:
Set the positive voltage supply to +15V and connect
to the VPOS test point.
Example to measure channel 8:
1) Set shunt J4 to the 2–3 (A3 = 0) position.
2) Set shunt J13 to the 1–2 (A2 = 1) position.
3) Set shunt J14 to the 1–2 (A1 = 1) position.
4) Set shunt J27 to the 1–2 (A0 = 1) position.
Set the negative voltage supply to -15V and connect
to the VNEG test point.
Connect the return of the power supply to the GND
test point.
2) Verify that all jumpers are in their default positions as
shown in Table 1.
5) Measure the on-resistance of channel 8 between the
NO8 and COMA test points.
3) Turn on the power supply. Ensure that both positive
and negative supplies have less than 1mA (max).

DG1206EUI+ by default. Engineers can request a sample
of DG1207EUI+ that can be soldered on the EV kit.
Detailed Description
The DG1206/DG1207 is the first member in the Maxim
low-leakage and low-charge-injection multiplexer family.
The DG120X EV kit has multiple SMA connectors, test
points, and jumpers for inputs and outputs, allowing easy
configuration and evaluation.
Every analog and digital channel has their own test
points. The two output channels have dedicated SMA
connectors; each four input channels share an SMA con-
nector. See Table 1 for the shunt positions to connect
SMA to correct analog channels.
The DG120X EV kit can be powered from either a bipolar
supply or a single supply with nominal voltage up to 20V.
Digital Inputs A3–A0, 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 3 to find the test point functions
when evaluating the DG1206 or DG1207.
Control Logic
The DG120X EV kit uses four selection inputs A3, A2, A1,
A0, and an enable input (EN) to determine the switching
logic. See the Control Logic section in DG1206/DG1207
data sheet for more information.

DG1206 or DG1207. The EV kit is populated with
