DG1208/DG1209
Low-Leakage, Single 8-Channel and Dual
4-Channel, Analog Multiplexers
General Description
Benefits and Features
The DG1208 and DG1209 are low-leakage, low-charge-
injection, single 8-channel or dual 4-channel multiplexing
switch devices. The DG1208 uses three selection inputs
A2, A1, and A0 to determine the switching logic; the
DG1209 uses two selection inputs A1 and A0. On both de-
vices, an enable (EN) input is used to enable or disable
the device.
● Distortion-Free Measurement
• 100Ω (typ) On Resistance
• ≤ 1nA (max) On/Off-Leakage Current at +85°C
• ≤ 0.5pC (typ) Charge Injection
● Wide Supply Range with Low Supply Current
• 40μA (typ) Quiescent Current at Room
Temperature
The low capacitance and low charge injection of the
DG1208/DG1209 make them ideal for automatic test
equipment systems, data acquisition systems and sample-
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
• GPIO-Compatible Control Inputs
• EN Input to Enable/Disable Device
• Available in both 16-TQFN and 16-TSSOP
Packages
The DG1208/DG1209 are available in 4mm x 4mm
16-lead TQFN or 16-lead TSSOP packages. The devices
are specified for operation over the -40°C to +85°C tem-
perature range.
• -40°C 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.

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/

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.

DG1208/DG1209
Low-Leakage, Single 8-Channel and Dual
4-Channel, Analog Multiplexers
Detailed Description
The DG1208/DG1209 are single 8-channel or dual 4-channel multiplexing switch devices with low leakage and low
charge injection. The low capacitance and low charge injection of the DG1208/DG1209 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 DG1208 is a single 8-channel multiplexer. It switches one of the 8 NO_ inputs to a common output COM, as
determined by the three selection inputs A2, A1, and A0. The DG1209 is a dual 4-channel multiplexer. It switches a pair
of differential NO_ inputs to differential outputs COMA and COMB, as determined by the two selection inputs A1 and A0.
See the Control Logic section for more information.
The DG1208/DG1209 operate rail-to-rail and are fully specified for ±15V bipolar supplies or +12V single supply. The EN
input on the DG1208/DG1209 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 DG1208 uses three selection inputs A2, A1, and A0 to determine the switching logic.
