Product details
Overview
DG1209EUE+T from Maxim Integrated is a dual 4-channel analog multiplexer IC designed for precision signal routing in high-fidelity data acquisition and test systems. It features rail-to-rail operation with ±15V bipolar or +12V single supply, ≤1nA max on/off-leakage at +85°C, 0.5pC typical charge injection, and 250MHz -3dB bandwidth-enabling low-glitch, fast-settling switching in differential signal paths.
For engineers reviewing the DG1209EUE+T datasheet, DG1209EUE+T pinout, DG1209EUE+T application, or DG1209EUE+T equivalent, key selection criteria include dual independent 4-channel architecture, GPIO-compatible A1/A0/EN control, TSSOP-16 package compatibility, and verified performance in sample-and-hold and communication system front-ends.
Technical Context
The DG1209EUE+T implements a dual independent analog switch matrix: each side (A and B) routes one of four NOx inputs to its respective COM terminal (COMA or COMB) using two address bits (A1, A0). Enable (EN) globally disables both sides simultaneously, ensuring no channel conduction when inactive.
Its architecture supports true bidirectional signal flow, rail-to-rail analog voltage range (VNEG to VPOS), and operates with <40μA quiescent current. The device maintains ≤30Ω on-resistance flatness and ≤10Ω match between channels under ±10V bias-critical for matched differential path integrity in instrumentation-grade designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Configuration | Dual 4-channel: independent A-side (NO1A–NO4A → COMA) and B-side (NO1B–NO4B → COMB) |
| On-Resistance (RON) | 100Ω typ (±15V), 165Ω typ (+12V); ensures minimal signal attenuation and gain error in precision gain stages |
| Charge Injection | 0.5pC typ; reduces voltage glitch and settling time in sample-and-hold circuits |
| Leakage Current | ≤1nA max at +85°C (on/off); preserves accuracy in high-impedance sensor interfaces and integrator nodes |
| -3dB Bandwidth | 250MHz (DG1209); supports wideband signal routing up to video and IF frequencies |
| Supply Range | ±15V bipolar or +12V single supply; enables flexible integration into mixed-signal systems with legacy analog rails |
| Control Inputs | A1, A0, EN: TTL/CMOS-compatible (VIH = 2.4V, VIL = 0.8V); simplifies interface with microcontrollers and FPGAs |
Pinout & Package
Package: 16-lead TSSOP (4.4mm × 5.0mm), RoHS-compliant, exposed pad not connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 | Address input bit 1: selects active channel pair (00→NO1A/NO1B, 01→NO2A/NO2B, etc.) |
| 2 | EN | Global enable: high = active switching; low = all channels open-circuit; must not float |
| 3 | VNEG | Negative supply rail: bypass to GND with ≥0.1μF ceramic capacitor; tied to GND in single-supply mode |
| 4 | NO1A | A-side channel 1 input/output: bidirectional, supports rail-to-rail analog signals |
| 5 | NO2A | A-side channel 2 input/output: matched to NO1A for differential pair routing |
| 6 | NO3A | A-side channel 3 input/output: identical electrical specs to NO1A/NO2A |
| 7 | NO4A | A-side channel 4 input/output: completes A-side 4-channel set |
| 8 | COMA | A-side common terminal: bidirectional I/O node for all A-side channels |
| 9 | NO1B | B-side channel 1 input/output: electrically isolated from A-side; used for complementary signal path |
| 10 | NO2B | B-side channel 2 input/output: enables simultaneous dual-path scanning |
| 11 | NO3B | B-side channel 3 input/output: supports independent addressing from A-side |
| 12 | NO4B | B-side channel 4 input/output: completes B-side 4-channel set |
| 13 | COMB | B-side common terminal: dedicated return path for B-side signals; prevents crosstalk with COMA |
| 14 | GND | Logic ground reference: connects to system digital ground plane; decoupling critical for noise immunity |
| 15 | VPOS | Positive supply rail: bypass to GND with ≥0.1μF ceramic capacitor; defines upper analog voltage limit |
| 16 | A0 | Address input bit 0: least-significant bit of 2-bit channel select code |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4-channel analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1409BRUZ | Higher RON (120Ω typ), higher charge injection (1.5pC), but wider supply range (±15V to ±22V) | Better suited for high-voltage industrial monitoring where leakage tolerance >2nA is acceptable | Select ADG1409BRUZ when extended overvoltage robustness is required and 0.5pC charge injection is not critical |
| TMUX1309PWR | Lower supply range (+12V only), lower leakage (0.5nA max), but reduced bandwidth (170MHz) | Optimized for battery-powered portable instrumentation with strict power budget (<15μA IQ) | Select TMUX1309PWR for low-power, single-supply portable DAQ where 250MHz bandwidth is unnecessary |
Compared with ADG1409BRUZ and TMUX1309PWR, the DG1209EUE+T uniquely balances ultra-low charge injection (0.5pC), 250MHz bandwidth, and dual independent channel control-making it optimal for high-fidelity, high-speed differential signal routing where both speed and precision are non-negotiable.

FAQ
What is the maximum operating temperature for DG1209EUE+T?
The DG1209EUE+T is specified for continuous operation from -40°C to +85°C ambient temperature. Its junction temperature must not exceed +150°C under any condition, and thermal design should account for θJA = 90°C/W (four-layer board) to ensure reliability within this range. Derating applies above +70°C ambient.
Does DG1209EUE+T support single-supply operation?
Yes, DG1209EUE+T fully supports +12V single-supply operation with VNEG connected to GND. All specifications-including on-resistance (165Ω typ), leakage (≤1nA), and bandwidth (250MHz)-are guaranteed under this configuration, enabling simplified power design in portable and cost-sensitive systems.
How does the dual-channel architecture of DG1209EUE+T differ from DG1208EUE+T?
DG1209EUE+T integrates two independent 4-channel multiplexers (A-side and B-side), each with its own COM terminal (COMA/COMB) and shared A1/A0/EN controls. In contrast, DG1208EUE+T is a single 8-channel mux with one COM terminal and three address lines (A2/A1/A0), making DG1209EUE+T ideal for differential or parallel signal routing where isolation between paths is essential.
What is the purpose of the exposed pad on DG1209EUE+T?
The exposed pad (EP) on DG1209EUE+T is not electrically connected and must be left unconnected per Maxim's datasheet. It serves only as a mechanical thermal relief structure and does not require soldering to ground or any other net-incorrect connection may compromise thermal performance or cause short circuits.
Can DG1209EUE+T handle rail-to-rail analog signals with ±15V supplies?
Yes, DG1209EUE+T supports true rail-to-rail analog signal operation from VNEG to VPOS. With ±15V supplies, it passes signals from -15V to +15V without clipping or distortion, and all key parameters-including leakage, on-resistance, and charge injection-are fully characterized across this full range per the datasheet's Electrical Characteristics tables.
