Product details
Overview
DG1206EUI+T from Analog Devices is a low-leakage, single 16-channel analog multiplexer IC with rail-to-rail operation, 100Ω typical on-resistance, ≤2nA max on/off-leakage current, and ≤0.5pC typical charge injection-designed for precision data acquisition systems requiring minimal signal distortion and fast settling.
For engineers reviewing the DG1206EUI+T datasheet, DG1206EUI+T pinout, DG1206EUI+T application, or DG1206EUI+T equivalent, this device supports ±15V bipolar or +12V single-supply operation, features GPIO-compatible address/enable inputs, and delivers -80dB off-isolation and 150MHz -3dB bandwidth in its 28-lead TSSOP package.
Technical Context
The DG1206EUI+T implements a 4-bit address-decoded 16:1 analog switch architecture using four logic-level selection inputs (A3–A0) and an active-high enable (EN) to control bidirectional signal routing between COM and any of 16 NOx terminals. It operates fully over -40°C to +85°C with rail-to-rail analog voltage support from VNEG to VPOS.
Its ultra-low 4pF NO_ off-capacitance, 15pF COM_ off-capacitance, and 10pF COM_ on-capacitance minimize charge redistribution and signal glitch during switching-critical for sample-and-hold and automatic test equipment where sub-400ns turn-on/turn-off times and <50ns break-before-make are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Count | Single 16-channel analog multiplexer - routes one of 16 bidirectional analog signals to common COM terminal. |
| On-Resistance (RON) | 100Ω typical at ±5V - ensures minimal voltage drop and gain error in precision measurement paths. |
| On/Off-Leakage Current | ≤2nA maximum at ±10V - preserves accuracy in high-impedance sensor interfaces and integrator circuits. |
| Charge Injection | ≤0.5pC typical - reduces settling time and pedestal error in sample-and-hold applications. |
| Supply Range | ±15V bipolar or +12V single supply - enables compatibility with legacy industrial and test equipment rails. |
| -3dB Bandwidth | 150MHz - supports high-speed signal routing without significant amplitude attenuation. |
| Off-Isolation / Crosstalk | -80dB at 1MHz - prevents channel-to-channel interference in multi-signal acquisition systems. |
Pinout & Package
Package: 28-lead TSSOP (5mm × 4.4mm), RoHS-compliant, exposed pad (EP) tied to VNEG or left floating-not connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| COM | Common analog I/O | Bidirectional signal path shared across all 16 channels; must be routed with controlled impedance for high-fidelity analog integrity. |
| NO1–NO16 | Normally-open analog I/O | 16 independent bidirectional analog terminals; each connects to COM only when selected by A3–A0 address code. |
| A0–A3 | Address inputs | 4-bit binary control (LSB A0) selecting one of 16 channels; compatible with 1.8V–5V logic levels (VIH = 2.4V, VIL = 0.8V). |
| EN | Enable input | Active-high global enable; drives all switches OFF when low-prevents unintended conduction during power-up or standby. |
| VPOS / VNEG | Analog supply rails | Supports ±15V bipolar or +12V/0V single supply; requires local 0.1µF ceramic bypassing per rail near pins 1 and 27. |
| GND | Logic ground reference | Reference for digital control inputs only; separate from analog signal return-avoid sharing with high-current analog paths. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog operation | Supports full-swing signals from VNEG to VPOS-enables direct interfacing with ±10V sensor outputs or DACs without level-shifting. |
| Ultra-low charge injection (≤0.5pC) | Minimizes voltage step errors in sample-and-hold amplifiers and integrators, reducing post-switching settling time. |
| Low on-resistance match (≤30Ω ΔRON) | Ensures consistent gain and offset across all 16 channels-critical for calibrated multi-channel data acquisition. |
| GPIO-compatible digital interface | Accepts standard CMOS logic levels (VIH = 2.4V, VIL = 0.8V) directly from microcontrollers or FPGAs-no level translators needed. |
| Break-before-make timing (50ns) | Prevents momentary shorting between channels during address transitions-essential for avoiding signal corruption in multiplexed sensor arrays. |

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, 3.3V/5V logic-compatible; higher 120Ω RON; same 28-TSSOP footprint but different pinout. | Targeted at lower-voltage, lower-channel-count systems; lacks ±15V support and rail-to-rail analog swing. | Select ADG1208BRUZ only if system uses 5V logic and requires fewer than 16 channels-DG1206EUI+T remains optimal for high-voltage, high-channel-count precision routing. |
| MAX4617ESE+ | 16-channel, ±15V rated; higher 200Ω RON; 10nA leakage; no charge injection spec provided. | Suitable for less demanding industrial switching; not recommended for sub-16-bit data acquisition due to higher RON and leakage. | Choose MAX4617ESE+ only for cost-sensitive, non-precision applications-DG1206EUI+T provides superior leakage, charge injection, and bandwidth for metrology-grade designs. |
Compared with ADG1208BRUZ and MAX4617ESE+, the DG1206EUI+T uniquely combines 16-channel count, ±15V rail-to-rail operation, ≤2nA leakage, and ≤0.5pC charge injection-making it the only option qualified for high-resolution, wide-dynamic-range multiplexing in ATE and scientific instrumentation.

FAQ
What supply voltages does the DG1206EUI+T support?
The DG1206EUI+T operates with ±15V bipolar supplies (VPOS = +15V, VNEG = -15V) or a +12V single supply (VNEG = GND). It supports rail-to-rail analog signal swings from VNEG to VPOS and specifies performance across the full -40°C to +85°C temperature range. Quiescent current is 40µA typical at room temperature under ±15V conditions.
How many analog channels does the DG1206EUI+T provide, and how is selection controlled?
The DG1206EUI+T provides a single 16-channel analog multiplexer function, routing one of 16 NOx inputs to the common COM terminal. Selection is controlled via four binary address inputs (A3, A2, A1, A0) and an active-high enable (EN) pin. When EN is high, the channel corresponding to the A3–A0 code conducts bidirectionally; when EN is low, all switches are disabled.
What is the maximum allowable leakage current for the DG1206EUI+T, and why does it matter?
The DG1206EUI+T specifies ≤2nA maximum on/off-leakage current at ±10V across the operating temperature range. This ultra-low leakage is critical in high-impedance applications such as electrometer-grade sensor interfaces, integrator circuits, and sample-and-hold amplifiers-where even picoamp-level currents cause measurable offset drift or hold-time degradation.
Does the DG1206EUI+T require external bypass capacitors, and where should they be placed?
Yes-the DG1206EUI+T requires a minimum 0.1µF ceramic capacitor placed as close as possible between VPOS and GND, and another between VNEG and GND. These bypass capacitors stabilize the analog supply rails, suppress high-frequency noise coupling, and prevent oscillation during fast switching transitions. The exposed pad (EP) may be left unconnected or tied to VNEG-but never to GND.
Can the DG1206EUI+T be used in audio or video signal routing applications?
Yes-the DG1206EUI+T is suitable for professional audio and composite video routing due to its 0.1% THD+N (20Hz–20kHz), -80dB off-isolation at 1MHz, 150MHz -3dB bandwidth, and rail-to-rail operation. Its low 4pF NO_ off-capacitance and 10pF COM_ on-capacitance minimize signal reflections and crosstalk, supporting clean switching of ±2Vpp line-level signals without audible artifacts or video ghosting.
