Product details
Overview
DG1206ETJ+ from Analog Devices is a low-leakage, single 16-channel analog multiplexer IC designed for precision signal routing in high-fidelity measurement paths. It features ≤2 nA max on/off-leakage current, 100 Ω typical on-resistance, ≤0.5 pC typical charge injection, and rail-to-rail operation with ±15 V bipolar or +12 V single supply - enabling distortion-free switching in automated test equipment front-ends.
For engineers reviewing the DG1206ETJ+ datasheet, DG1206ETJ+ pinout, DG1206ETJ+ application, or DG1206ETJ+ equivalent, key selection criteria include ultra-low leakage performance at full signal swing, fast settling (<400 ns turn-on), 150 MHz -3dB bandwidth, and compatibility with GPIO-level control logic across industrial temperature range (-40°C to +85°C).
Technical Context
The DG1206ETJ+ implements a 4-bit address-decoded 1:16 bidirectional analog switch matrix, where A3–A0 select one of 16 NOx inputs to connect to the common COM terminal. Its CMOS-based switch architecture delivers rail-to-rail analog conduction and supports both bipolar (±15 V) and single-supply (+12 V) operation without performance degradation.
Enable (EN) provides global channel disable with zero-current leakage state; all switches are fully off when EN = low. Charge injection (≤0.5 pC typ) and off-capacitance (4 pF NO_, 15 pF COM_) are minimized to reduce glitch energy and maintain fast settling in sample-and-hold and data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Count | Single 16-channel analog multiplexer - routes one of 16 bidirectional analog signals to shared COM node. |
| On-Resistance (RON) | 100 Ω typical at ±5 V - ensures minimal signal attenuation and gain error in precision measurement paths. |
| On/Off-Leakage Current | ≤2 nA max at ±10 V - preserves accuracy in high-impedance sensor interfaces and integrator circuits. |
| Charge Injection | ≤0.5 pC typical - limits voltage glitch on hold capacitors, critical for sub-16-bit ADC sampling fidelity. |
| -3dB Bandwidth | 150 MHz - supports wideband signal routing up to ~50 MHz fundamental without significant amplitude loss. |
| Supply Range | ±15 V bipolar or +12 V single supply - enables direct interfacing with legacy industrial signal chains and modern low-voltage controllers. |
| Operating Temp | -40°C to +85°C - qualified for deployment in industrial automation, test rack, and embedded DAQ environments. |
Pinout & Package
Package: 32-lead 5 mm × 5 mm TQFN (exposed pad), RoHS-compliant, thermal resistance θJA = 29°C/W (4-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| COM (Pin 29) | Common analog terminal | Bidirectional signal path shared across all 16 channels; must be routed with controlled impedance and low parasitic capacitance. |
| NO1–NO16 (Pins 1–8, 17–24, 26) | Normally-open analog terminals | 16 independent bidirectional analog I/Os; each connects to COM only when selected by A3–A0 address. |
| A0–A3 (Pins 15–10) | Binary address inputs | 4-bit parallel select bus; compatible with 1.8 V–5 V GPIO logic levels (VIH = 2.4 V, VIL = 0.8 V). |
| EN (Pin 16) | Global enable input | Active-high control: drives all switches OFF when low; eliminates need for external power gating in standby modes. |
| VPOS (Pin 31), VNEG (Pin 25), GND (Pin 9) | Power supply terminals | Support ±15 V bipolar or +12 V single supply; requires local 0.1 µF ceramic bypassing per supply pin. |
| NC (Pins 3, 4, 5, 6, 7, 12, 13, 26, 27, 28, 30, 32) | No-connect pins | Internally unconnected; must remain floating or grounded per PCB layout best practices to avoid noise coupling. |
| EP (Exposed Pad) | Thermal pad | May be left unconnected or tied to VNEG; never connected to GND to prevent ground loop and thermal stress. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low leakage | ≤2 nA max on/off-leakage ensures <0.001% error in 1 MΩ source impedance applications at ±10 V. |
| Rail-to-rail analog range | Full signal swing from VNEG to VPOS enables seamless integration with ±10 V instrumentation amplifiers and DACs. |
| GPIO-compatible control | A0–A3 and EN accept standard 3.3 V/5 V logic without level-shifting, simplifying microcontroller interface design. |
| Low-charge-injection switching | ≤0.5 pC typical minimizes hold-step error in precision sample-and-hold circuits using ≥100 pF capacitors. |
| High off-isolation | -80 dB at 1 MHz ensures >10,000:1 crosstalk suppression between unselected channels in dense multiplexed 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, 0.5 pC charge injection, 120 Ω RON, 28-TSSOP package | Half the channel count; lacks A3 input and 16:1 topology - suitable only for 8-input systems | Select when board space or channel density permits reduced count and lower cost is prioritized over 16-channel consolidation. |
| MAX4617ESE+ | 16-channel, 2.5 nA leakage, 200 Ω RON, 28-SOIC package | Higher on-resistance and leakage; SOIC footprint increases PCB area vs. 5×5 mm TQFN | Choose for through-hole prototyping or legacy SOIC-compatible designs where thermal performance is secondary. |
Compared with ADG1208BRUZ and MAX4617ESE+, the DG1206ETJ+ uniquely combines 16-channel density, ≤2 nA leakage, and 5×5 mm TQFN packaging - delivering highest channel-per-mm² ratio and lowest leakage among pin-compatible alternatives for space-constrained, high-accuracy DAQ front-ends.

FAQ
What is the maximum allowable supply voltage for DG1206ETJ+?
The DG1206ETJ+ supports absolute maximum ratings of VPOS to GND = −0.3 V to +20.5 V and VNEG to GND = −20.5 V to +0.3 V. For reliable operation, Analog Devices specifies continuous use within ±15 V bipolar supplies or +12 V single supply. Exceeding these ranges risks permanent damage, even if within absolute maximum limits.
Does DG1206ETJ+ support single-supply operation with VNEG tied to GND?
Yes, DG1206ETJ+ supports single-supply operation: tie VNEG to GND and apply +10 V to +20 V to VPOS (typically +12 V). The device maintains rail-to-rail analog signal range (0 V to VPOS), 100 Ω typical on-resistance, and ≤2 nA leakage under these conditions - confirmed in Electrical Characteristics tables for +12 V supply.
How does the EN pin function in DG1206ETJ+?
The EN pin is an active-high enable input. When EN = low (≤0.8 V), all 16 switches are fully disabled with ≤2 nA leakage. When EN = high (≥2.4 V), channel selection proceeds normally via A3–A0. Leaving EN unconnected is prohibited - it must be actively driven to avoid undefined switching states.
What is the purpose of the exposed pad (EP) on DG1206ETJ+?
The exposed pad (EP) on DG1206ETJ+ serves a thermal function. It may be left unconnected or tied to VNEG to improve heat dissipation; however, connecting EP to GND is strictly prohibited as it creates a thermal and electrical mismatch that degrades reliability and may cause parametric shift under thermal cycling.
Can DG1206ETJ+ be used in differential signal routing applications?
No - DG1206ETJ+ is a single-ended 16:1 multiplexer with one COM terminal. For differential routing, Analog Devices specifies the DG1207 (dual 8-channel) variant, which provides separate COMA/COMB outputs and paired NOxA/NOxB inputs. Using DG1206ETJ+ for differential signals would require two devices and introduces timing skew and mismatch.
