Product details
Overview
DG1206ETJ+ 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 automatic test equipment and sample-and-hold systems.
For engineers reviewing the DG1206ETJ+ datasheet, DG1206ETJ+ pinout, DG1206ETJ+ application, or DG1206ETJ+ equivalent, key selection considerations include its 32-lead TQFN package, four-bit address decoding (A3–A0), enable-controlled channel activation, and verified performance in low-glitch, fast-settling analog front-ends requiring sub-nA leakage and pC-level charge injection control.
Technical Context
The DG1206ETJ+ implements a single-pole, 16-throw (16:1) analog switch architecture with CMOS-based transmission gates optimized for ultra-low charge injection and off-capacitance. Its address decoder accepts four binary inputs (A3–A0) to select one of 16 bidirectional NOx channels to connect to the common COM terminal.
Rail-to-rail analog signal handling (VNEG to VPOS), GPIO-compatible digital inputs (VIH = 2.4V, VIL = 0.8V), and EN-driven global disable functionality support integration into mixed-signal systems without level-shifting. The device operates across –40°C to +85°C and is fully specified under both ±15V bipolar and +12V single-supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Count | Single 16-channel (16:1) analog multiplexer - routes one of 16 bidirectional analog signals to a shared COM node. |
| On-Resistance (RON) | 100Ω typical at ±5V, 1mA - ensures minimal signal attenuation and gain error in precision measurement paths. |
| On/Off-Leakage Current | ≤2nA maximum 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 during channel switching, critical for ADC input settling. |
| Supply Range | Fully specified for ±15V bipolar or +12V single supply - supports legacy industrial bipolar rails and modern low-voltage systems. |
| Turn-On/Off Time | 200ns/300ns typical (±15V) - enables high-throughput scanning in automated test equipment with tight timing budgets. |
| Off Isolation | –80dB at 1MHz - suppresses crosstalk between unselected channels in dense multiplexed signal chains. |
Pinout & Package
DG1206ETJ+ is housed in a 5mm × 5mm, 32-lead TQFN package (package code T3255+4) with exposed pad (EP) - recommended to be left floating or tied to VNEG, not GND. Thermal resistance is 47°C/W (θJA, single-layer board) and 29°C/W (θJA, four-layer board).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| COM (Pin 29) | Common analog terminal | Bidirectional I/O node - connects to ADC input, DAC output, or instrumentation amplifier in shared-path architectures. |
| NO1–NO16 (Pins 1–8, 17–24, 29) | Normally-open analog terminals | 16 independent bidirectional analog signal paths - each isolated when unselected; no internal pull-downs or terminations. |
| A0–A3 (Pins 15–10) | Address selection inputs | 4-bit binary control bus - determines active channel (0–15); compatible with 1.8V/3.3V/5V logic levels (VIH = 2.4V min). |
| EN (Pin 16) | Global enable input | Active-high logic control - drives all switches OFF when low; prevents unintended conduction during power-up or reset. |
| VPOS (Pin 31), VNEG (Pin 25), GND (Pin 9) | Analog power rails | Supports ±15V bipolar operation or +12V single supply (VNEG = GND); requires local 0.1μF ceramic bypassing per rail. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low charge injection | ≤0.5pC typical - reduces hold-step error in sample-and-hold circuits and maintains DC accuracy after switching. |
| Rail-to-rail analog range | VNEG to VPOS - preserves full dynamic range of ±10V or 0–12V input signals without clipping or headroom loss. |
| Sub-nA leakage performance | ≤2nA max on/off leakage at ±10V - avoids drift in high-Z sensor nodes and long-time-constant integrators. |
| GPIO-compatible digital interface | VIH = 2.4V, VIL = 0.8V - directly interfaces with microcontrollers, FPGAs, and ASICs without level shifters. |
| Break-before-make timing | 50ns typical - eliminates momentary short-circuits between channels during address transitions, preventing signal corruption. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1206BRUZ | 28-lead TSSOP package; identical electrical specs but different pinout and thermal resistance (θJA = 71.6°C/W vs. 29°C/W). | Preferred where PCB space allows larger footprint and lower-cost assembly; less suitable for high-power-density layouts. | Select ADG1206BRUZ only if TSSOP compatibility and cost outweigh thermal performance needs. |
| MAX4617ESE+ | 16-channel mux with higher on-resistance (120Ω typ), higher leakage (5nA max), and no ±15V rating - rated only for +12V single supply. | Suitable for lower-precision, cost-sensitive consumer-grade DAQ - not viable for ATE or bipolar-rail industrial use. | Choose MAX4617ESE+ only for non-critical, single-supply applications where leakage and charge injection tolerances are relaxed. |
Compared with ADG1206BRUZ and MAX4617ESE+, DG1206ETJ+ delivers superior thermal performance in compact layouts, guaranteed ±15V operation, and lowest-in-class leakage/charge injection - making it the optimal choice for high-reliability, high-accuracy multiplexing where signal fidelity is non-negotiable.

FAQ
What is the maximum allowable supply voltage for DG1206ETJ+?
DG1206ETJ+ supports absolute maximum ratings of VPOS to GND = –0.3V to +20.5V and VNEG to GND = –20.5V to +0.3V, with continuous operation fully specified at ±15V bipolar supplies or +12V single supply. Exceeding ±15V or +12V may compromise parametric guarantees and reliability - always observe derating curves in the datasheet for extended voltage or temperature operation.
Does DG1206ETJ+ support rail-to-rail analog signal switching?
Yes, DG1206ETJ+ supports true rail-to-rail analog signal switching across its full specified supply range: signals from VNEG to VPOS are passed without clipping or distortion. This includes ±10V differential ranges under ±15V supplies and 0–12V ranges under +12V single supply - confirmed by THD+N ≤0.1% and flat on-resistance over full voltage swing.
How many address lines does DG1206ETJ+ require to select channels?
DG1206ETJ+ requires four address lines - A3, A2, A1, and A0 - to decode and select one of its 16 analog channels. The control logic table confirms binary mapping from 0000 to 1111 (decimal 0–15), with EN = high required for any channel to conduct. All address inputs are CMOS-compatible with VIH ≥2.4V and VIL ≤0.8V.
Can DG1206ETJ+ be used in single-supply configurations?
Yes, DG1206ETJ+ is fully specified for +12V single-supply operation with VNEG connected to GND. In this mode, analog signals swing from 0V to +12V, on-resistance remains 165Ω typical, and leakage stays ≤2nA max - validated per Electrical Characteristics tables for +12V conditions. Bypassing VPOS and GND with 0.1μF ceramics remains mandatory.
What is the purpose of the exposed pad (EP) on DG1206ETJ+?
The exposed pad (EP) on DG1206ETJ+ serves as a thermal interface - it must be left unconnected or tied to VNEG (not GND) to optimize heat dissipation. Per Analog Devices' package documentation, connecting EP to GND risks increased thermal resistance and potential latch-up. Layout guidelines recommend soldering EP to a dedicated thermal land with thermal vias to inner ground or VNEG planes.
