Product details
Overview
DG1206EUI+ from Analog Devices is a low-leakage, single 16-channel analog multiplexer IC used for precision signal routing in high-fidelity data acquisition paths. It features 100Ω typical on-resistance, ≤2nA max on/off-leakage current at ±10V, ≤0.5pC typical charge injection, and rail-to-rail operation with ±15V bipolar or +12V single supply - enabling distortion-free switching in sample-and-hold and automatic test equipment.
For engineers reviewing the DG1206EUI+ datasheet, DG1206EUI+ pinout, DG1206EUI+ application, or DG1206EUI+ equivalent, key selection criteria include ultra-low leakage performance, 16-channel address decoding via A3–A0, EN-controlled global enable/disable, and compatibility with both TSSOP-28 and TQFN-32 packages across –40°C to +85°C.
Technical Context
The DG1206EUI+ implements a CMOS-based 16:1 analog multiplexer architecture with four binary address inputs (A3–A0) selecting one of sixteen bidirectional NOx terminals to connect to the common COM terminal. Its control logic supports break-before-make switching and full disable via EN input.
Designed for precision analog signal paths, it delivers rail-to-rail signal handling, ultra-low off-capacitance (4pF NO_ off, 15pF COM_ off), and fast settling due to low charge injection (≤0.5pC typ) and low on-resistance flatness (17Ω typ), making it suitable for high-resolution ADC front-ends and low-glitch instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Count | Single 16-channel analog multiplexer - routes one of 16 inputs to shared COM terminal. |
| On-Resistance (RON) | 100Ω typical at ±5V - ensures minimal signal attenuation and gain error in precision measurement paths. |
| On/Off-Leakage Current | ≤2nA max at ±10V - preserves accuracy in high-impedance sensor interfaces and sample-and-hold hold capacitors. |
| Charge Injection | ≤0.5pC typical - minimizes voltage glitch on hold capacitors, critical for sub-LSB settling in 16-bit+ systems. |
| Supply Range | Fully specified for ±15V bipolar or +12V single supply - supports both industrial bipolar and compact single-rail designs. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and automated test environments without derating. |
| Turn-On/Off Time | 200ns/300ns typical (±15V) - enables high-throughput channel scanning in ATE and DAQ systems. |
Pinout & Package
Package: 28-lead TSSOP (U28+2), 9.7mm × 4.4mm body, 0.65mm pitch, exposed pad (EP) tied to VNEG or left floating - optimized for thermal dissipation and board space efficiency in dense mixed-signal layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| COM | Common analog terminal | Bidirectional signal path shared across all 16 channels; connects to ADC input or signal processor. |
| NO1–NO16 | Analog input/output terminals | 16 normally-open bidirectional ports; each independently selectable to COM via A3–A0 address bus. |
| A0–A3 | Binary address inputs | 4-bit parallel interface determining active channel (0–15); GPIO-compatible (VIH = 2.4V, VIL = 0.8V). |
| EN | Global enable input | Active-high logic control: EN = low disables all switches (high-impedance state), EN = high enables addressing. |
| VPOS / VNEG | Power rails | Supports ±15V bipolar operation or +12V single supply (VNEG = GND); requires local 0.1μF ceramic bypassing. |
| GND | Logic reference | Ground reference for digital control signals; separate from analog signal ground in mixed-signal layouts. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low leakage | ≤2nA max on/off-leakage at ±10V - prevents drift in high-Z sample-and-hold circuits and thermocouple amplifiers. |
| Rail-to-rail signal range | Full analog swing from VNEG to VPOS - preserves dynamic range in ±15V sensor conditioning and DAC output routing. |
| Low charge injection | ≤0.5pC typical - reduces required hold capacitor size and settling time in precision data acquisition front-ends. |
| GPIO-compatible control | VIH = 2.4V, VIL = 0.8V - allows direct interfacing with 3.3V/5V microcontrollers without level-shifting. |
| Break-before-make switching | 50ns typical tBBM - eliminates momentary short-circuits between channels during address transitions. |
Applications
| Automatic Test Equipment (ATE) | Data Acquisition Systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1208BRUZ | 8-channel, ±15V-rated, 120Ω RON, 1.5nA leakage - smaller channel count, higher RON. | Suitable for lower-density routing where 8:1 suffices and layout space is constrained. | Select when system requires only 8 inputs and tighter board area; verify leakage tolerance against hold capacitor size. |
| MAX4617ESE+ | 16-channel, +12V single-supply only, 125Ω RON, 5nA leakage - no bipolar support, higher leakage. | Applicable in cost-sensitive, single-rail industrial controllers where ±15V is unavailable. | Choose only for +12V-only systems accepting higher leakage; not suitable for precision bipolar signal chains. |
Compared with ADG1208BRUZ and MAX4617ESE+, the DG1206EUI+ uniquely combines 16-channel count, bipolar ±15V capability, ≤2nA leakage, and ≤0.5pC charge injection - making it the only option for high-accuracy, wide-dynamic-range multiplexing in ATE and metrology-grade DAQ.

FAQ
What is the maximum allowable supply voltage for DG1206EUI+?
The DG1206EUI+ supports absolute maximum ratings of VPOS to GND = –0.3V to +20.5V and VNEG to GND = –20.5V to +0.3V. For reliable operation, use ±15V bipolar supplies or +12V single supply (with VNEG = GND), as fully characterized in the datasheet. Exceeding these ranges risks permanent damage.
Does DG1206EUI+ support rail-to-rail analog signal switching?
Yes, DG1206EUI+ supports true rail-to-rail analog signal operation - signals can swing from VNEG to VPOS without clipping. This is verified across its full –40°C to +85°C temperature range and applies to both ±15V bipolar and +12V single-supply configurations.
How does the EN pin function on DG1206EUI+?
The EN pin on DG1206EUI+ is an active-high enable input. When EN is driven low (≤0.8V), all 16 channels are disabled into high-impedance state regardless of A3–A0 address. When EN is high (≥2.4V), channel selection proceeds normally per the address inputs. Leaving EN unconnected is prohibited.
What is the thermal resistance of DG1206EUI+ in its TSSOP package?
In the 28-TSSOP package (DG1206EUI+), junction-to-ambient thermal resistance (θJA) is 71.6°C/W on a four-layer PCB and 78°C/W on a single-layer board. Junction-to-case (θJC) is 13°C/W. These values inform thermal design for continuous operation at full rated supply voltages.
Can DG1206EUI+ be used with a 3.3V microcontroller for address control?
Yes, DG1206EUI+ has GPIO-compatible digital inputs: VIH = 2.4V (min) and VIL = 0.8V (max), making it directly compatible with standard 3.3V logic. No level-shifting is required for A0–A3 or EN signals when driven from 3.3V microcontrollers or FPGAs.
