DG1206/DG1207
Low-Leakage, Single 16-Channel and
Dual 8-Channel, Analog Multiplexer
General Description
Benefits and Features
The DG1206 and DG1207 are low-leakage, low-charge-
injection single 16-channel or dual 8-channel multiplexing
switch devices. The DG1206 uses four selection inputs
A3, A2, A1, and A0 to determine the switching logic; the
DG1207 uses three selection inputs A2, A1, and A0. On
both devices, an enable (EN) input is used to enable or
disable the device.
● Distortion-Free Measurement
• 100Ω (typ) On Resistance
• ≤ 2nA (max) On/Off-Leakage Current for DG1206
• ≤ 1nA (max) On/Off-Leakage Current for DG1207
• ≤ 0.5pC (typ) Charge Injection
● Wide Supply Range with Low Supply Current
• 40μA (typ) Quiescent Current at Room
Temperature
The ultra-low capacitance and low-charge injection of the
DG1206/DG1207 make them ideal for automatic test
equipment systems, data acquisition systems, and sam-
ple-and-hold systems where low glitch and fast settling
time are required.
• Fully Specified with ±15V Bipolar Supplies or +12V
Single Supply
• Rail-to-Rail Operation
● Flexible Design Option
The DG1206/DG1207 are available in 5mm x 5mm
32-lead TQFN or 28-lead TSSOP packages. The devices
are specified for operation over the -40°C to +85°C tem-
perature range.
• GPIO-Compatible Control Inputs
• EN Input to Enable/Disable Device
• Available in both 32-TQFN and 28-TSSOP
Packages
• -40ºC to +85°C Temperature Range
Applications
Ordering Information appears at end of data sheet.
● Automatic Test Equipment Systems
● Data Acquisition Systems
● Sample-and-Hold Systems
● Communication Systems
● Audio and Video Routing

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the
device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.

For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages. Note that a “+”, “#”, or “-” in the package code indicates
RoHS status only. Package drawings may show a different suffix character, but the drawing pertains to the package regardless of RoHS status.
Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board. For detailed information on package thermal
considerations, refer to www.maximintegrated.com/thermal-tutorial.

on. The output (COM_) is sourced with 1mA current while biased at one of these levels: 0V, ±5V, or ±10V.
Note 3: On-Resistance Flatness (R ) is measured when the output channel is turned on. The output (COM_) is sourced with 1mA

current while biased at one of these levels: -5V, 0V, or +5V.
Note 4: NO_ Off-Leakage Current (I ) is measured when the output channel is switched off while the input (NO_) is biased at
NO_OFF
+10V and output (COM_) at -10V, or while the input is biased at -10V and output at +10V.
Note 5: COM_ Off-Leakage Current (I ) is measured when the output channel is switched off while the input (NO_) is biased
COM_OFF
at +1V and output (COM_) at +10V, or while the input is biased at +10V and output at +1V.

DG1206/DG1207
Low-Leakage, Single 16-Channel and
Dual 8-Channel, Analog Multiplexer
Detailed Description
The DG1206/DG1207 are single 16-channel or dual 8-channel multiplexing switch devices with low-leakage and low-
charge injection. The ultra-low capacitance and low-charge injection of the DG1206/DG1207 make them ideal for
automatic test equipment systems, data acquisition systems, sample-and-hold systems, and communication systems
where low glitch and fast settling time are required.
The DG1206 is a single 16-channel multiplexer. It switches one of the 16 NO_ inputs to a common output COM, as
determined by the four selection inputs A3, A2, A1, and A0. The DG1207 is a dual 8-channel multiplexer. It switches a
pair of differential NO_ inputs to differential outputs COMA and COMB, as determined by the three selection inputs A2,
A1, and A0. See the Control Logic section for more information.
The DG1206/DG1207 operate rail-to-rail and are fully specified for ±15V bipolar supplies or +12V single supply. The EN
input on DG1206/DG1207 is used to enable or disable the device. When EN is low, all channels are switched off. When
EN is high, each channel conducts bidirectionally according to the selection inputs.
Control Logic
The DG1206 uses four selection inputs A3, A2, A1, and A0 to determine the switching logic.
