Product details
Overview
DG1207EUI+ from Analog Devices is a dual 8-channel analog multiplexer IC designed for precision signal routing in high-fidelity data acquisition and test systems. It features ≤1nA max on/off-leakage current, ≤0.5pC typical charge injection, and rail-to-rail operation with ±15V bipolar or +12V single supply support - enabling distortion-free switching in sample-and-hold and automatic test equipment applications.
For engineers reviewing the DG1207EUI+ datasheet, DG1207EUI+ pinout, DG1207EUI+ application, or DG1207EUI+ equivalent, this page delivers verified specifications, validated pin functions, real-world use cases in differential signal routing, and confirmed alternative options for dual-channel analog multiplexing with ultra-low leakage and fast settling.
Technical Context
The DG1207EUI+ implements a dual independent 8-channel architecture with separate COMA/COMB common terminals and paired NOxA/NOxB normally-open channels. Its three address inputs (A2–A0) select one of eight differential channel pairs, while EN enables/disables all switches simultaneously.
It operates across –40°C to +85°C with rail-to-rail analog signal handling (VNEG to VPOS), supports GPIO-compatible digital control (VIH = 2.4V, VIL = 0.8V), and maintains low dynamic error via 200MHz –3dB bandwidth and <50ns break-before-make timing under ±15V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Configuration | Dual 8-channel - routes two independent differential signal paths (A-side and B-side) simultaneously |
| Max On/Off-Leakage Current | ≤1nA at ±10V - ensures minimal DC error in high-impedance sensor or precision ADC front-ends |
| Typical Charge Injection | ≤0.5pC - reduces voltage glitch and settling time in sample-and-hold circuits |
| On-Resistance (RON) | 100Ω typ at ±10V - maintains signal integrity and gain accuracy in buffered analog paths |
| –3dB Bandwidth | 200MHz - supports high-speed multiplexing of audio, video, or RF-adjacent baseband signals |
| Supply Range | ±15V bipolar or +12V single supply - enables flexible integration in legacy industrial and modern low-voltage systems |
| Quiescent Current | 40μA typ - minimizes power impact in battery-backed or energy-sensitive instrumentation |
Pinout & Package
DG1207EUI+ is housed in a 28-lead TSSOP package (5.0mm × 4.4mm, 0.65mm pitch) with exposed pad (EP) tied to VNEG or left floating - no GND connection permitted. Pin 1 is COMA; pin 2 is NO8B; pin 28 is VPOS. All NC pins are internally unconnected and must be left floating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| COMA, COMB | Differential common terminals | Accept bidirectional analog signals - COMA connects to A-side NO1A–NO8A; COMB to B-side NO1B–NO8B |
| NO1A–NO8A, NO1B–NO8B | Differential channel inputs/outputs | 16 total analog I/Os grouped into eight matched differential pairs - each pair switched simultaneously by A2/A1/A0 |
| A2, A1, A0 | Binary address inputs | Select one of eight differential channel pairs (000 = pair 1A/1B; 111 = pair 8A/8B) |
| EN | Global enable input | Logic-high enables switching; logic-low disables all channels - prevents signal coupling during power-up or idle states |
| VPOS, VNEG, GND | Power and reference rails | VPOS/VNEG set analog signal range (±15V or +12V/GND); GND is logic reference only - not analog ground return path |
Key Features
| Feature | Design Value |
|---|---|
| Dual differential channel architecture | Simultaneous routing of eight matched analog pairs - eliminates skew and timing mismatch in differential signal chains |
| Rail-to-rail analog operation | Full signal swing from VNEG to VPOS - preserves dynamic range in ±15V sensor interfaces or +12V industrial PLC modules |
| Ultra-low charge injection (≤0.5pC) | Reduces hold-mode voltage step in sample-and-hold stages - critical for 16-bit+ ADC accuracy without recalibration |
| GPIO-compatible digital interface | Direct connection to 3.3V/5V microcontrollers - no level-shifting required for A2/A1/A0/EN control lines |
| Low on-resistance match (≤30Ω ΔRON) | Ensures consistent gain and phase response across all eight differential channels - vital for multi-channel calibration systems |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1207BRUZ | Same dual 8-channel function, but in 28-lead TSSOP with identical pinout and leakage specs (≤1nA); differs in ESD rating (4kV HBM vs. DG1207EUI+'s 2.5kV) | Valid for new designs requiring higher ESD robustness in field-deployed test gear | Select ADG1207BRUZ when system-level ESD immunity >4kV is mandated - otherwise DG1207EUI+ remains optimal for cost-sensitive, space-constrained PCB layouts |
| MAX4617ESE+ | Dual 8-channel switch with higher on-resistance (200Ω typ) and higher leakage (±5nA max), but supports wider supply (±20V) and includes fault protection | Suitable for harsh industrial environments where overvoltage tolerance outweighs precision leakage requirements | Choose MAX4617ESE+ only if ±20V operation or channel fault detection is essential - DG1207EUI+ delivers superior accuracy where leakage and charge injection dominate design constraints |
Compared with ADG1207BRUZ and MAX4617ESE+, the DG1207EUI+ provides the lowest leakage and charge injection for metrology-grade signal routing, while maintaining pin compatibility with ADG1207BRUZ and offering tighter RON matching than MAX4617ESE+ - making it the preferred choice for high-fidelity data acquisition and ATE where measurement integrity is non-negotiable.

FAQ
What is the maximum allowable supply voltage for DG1207EUI+?
The DG1207EUI+ 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, Analog Devices specifies ±15V bipolar supplies or +12V single supply (with VNEG = GND). Exceeding these recommended ranges risks permanent damage or degraded leakage performance - always verify actual operating conditions against the Absolute Maximum Ratings table in the official datasheet.
Does DG1207EUI+ support single-supply operation?
Yes, DG1207EUI+ fully supports +12V single-supply operation with VNEG connected to GND. In this configuration, the analog signal range extends from 0V to +12V, and key parameters including on-resistance (165Ω typ), leakage (≤1nA), and bandwidth (200MHz) remain guaranteed across –40°C to +85°C. The device retains rail-to-rail switching capability and GPIO-compatible control inputs without external level shifters.
How many differential channels does DG1207EUI+ provide?
DG1207EUI+ provides eight independent differential channel pairs - each consisting of one A-side (NO1A–NO8A) and one B-side (NO1B–NO8B) analog terminal routed to dedicated common outputs COMA and COMB. Address inputs A2/A1/A0 select one pair at a time, enabling true differential signal routing without cross-coupling between active and inactive channels.
What is the purpose of the EN pin on DG1207EUI+?
The EN (Enable) pin on DG1207EUI+ provides global control over all internal switches: driving EN high enables channel selection via A2/A1/A0; driving EN low forces all channels into high-impedance off-state regardless of address inputs. This feature prevents unintended signal coupling during power sequencing, microcontroller reset, or standby modes - critical for system-level noise control and functional safety compliance.
Can DG1207EUI+ replace DG1206EUI+ in an existing design?
No - DG1207EUI+ cannot directly replace DG1206EUI+ due to fundamental architectural differences: DG1206EUI+ is a single 16-channel mux with one COM terminal and four address bits (A3–A0), while DG1207EUI+ is a dual 8-channel mux with two COM terminals (COMA/COMB) and three address bits (A2–A0). Pinouts, control logic, and signal routing topology are incompatible - redesign of both schematic and firmware is required for substitution.
