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-chargeinjection, 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 devices, 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
The low capacitance and low charge injection of the
DG1208/DG1209 make them ideal for automatic test
equipment systems, data acquisition systems and sampleand-hold systems where low glitch and fast settling time
are required.
● Wide Supply Range with Low Supply Current
• 40μA (typ) Quiescent Current at Room
Temperature
• Fully Specified with ±15V Bipolar Supplies or +12V
Single Supply
• Rail-to-Rail Operation
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 temperature range.
● Flexible Design Option
• GPIO-Compatible Control Inputs
• EN Input to Enable/Disable Device
• Available in both 16-TQFN and 16-TSSOP
Packages
• -40°C to +85°C Temperature Range

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 1: Limits are 100% tested at TA = +85°C. Limits over the operating temperature range and relevant supply-voltage range are
guaranteed by design and characterization.
Note 2: On Resistance (RON) and On-Resistance Match Between Channels (ΔRON) are measured when the output channel is turned
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 (RFLAT) 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 (INO_OFF) is measured when the output channel is switched off while the input (NO_) is biased at
+10V and output (COM_) at -10V, or while the input is biased at -10V and output at +10V.
Note 5: COM_ Off-Leakage Current (ICOM_OFF) is measured when the output channel is switched off while the input (NO_) is biased
at +1V and output (COM_) at +10V, or while the input is biased at +10V and output at +1V.
Note 6: On Resistance (RON), On-Resistance Match Between Channels (ΔRON), and On-Resistance Flatness (RFLAT) are measured
when the output channel is turned on. The output (COM_) is sourced with 1mA current while biased at one of these levels: 3V,
6V, or 9V.
Note 7: NO_ Off-Leakage Current (INO_OFF) and COM_ Off-Leakage Current (ICOM_OFF) are measured when the output channel is
switched off while the input (NO_) is biased 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.
