Product details
Overview
DG1209ETE+ 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 DG1209ETE+ datasheet, DG1209ETE+ pinout, DG1209ETE+ application, or DG1209ETE+ equivalent, this page delivers verified specifications, dual-channel control logic, TQFN-16 package details, thermal resistance data, and real-world design context for automatic test equipment, sample-and-hold circuits, and differential audio/video routing.
Technical Context
The DG1209ETE+ implements a dual independent 4:1 analog multiplexer architecture: each side (A and B) routes one of four NOx inputs to its dedicated COM terminal using two address bits (A1, A0). Control is synchronous and bidirectional, with EN enabling/disabling both sides simultaneously.
Rail-to-rail analog signal handling supports input ranges from VNEG to VPOS, with guaranteed performance across -40°C to +85°C. Its low 4pF NO_ off-capacitance and 15pF COM_ off-capacitance minimize crosstalk (-80dB) and off-isolation degradation, while break-before-make timing (50ns) prevents channel shorting during switching.
Key Specifications

| Turn-On/Off Time | 200–600ns depending on supply-balances speed and charge-injection trade-offs for system-level settling requirements |
Pinout & Package
Package: 16-pin TQFN (4mm × 4mm, exposed pad), RoHS-compliant, rated for -40°C to +85°C operation. Thermal resistance θJA = 40°C/W (4-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3 | VNEG | Negative power supply rail; must be bypassed with ≥0.1µF ceramic capacitor to GND-critical for noise rejection in bipolar operation |
| 2, 4 | NO1A, NO1B | A-side and B-side channel 1 analog inputs/outputs-support differential pair routing when used together |
| 5, 7 | NO4A, NO4B | A-side and B-side channel 4 analog terminals-identical electrical characteristics to NO1x for matched channel performance |
| 6, 8 | COMA, COMB | Independent common terminals per side-enable true dual-path signal selection without inter-channel coupling |
| 9, 11 | NO3B, NO2B | B-side channels 3 and 2-pin-ordered to support compact PCB layout with minimized trace length mismatch |
| 10, 12 | NO3A, NO2A | A-side channels 3 and 2-mirror B-side pinout for symmetrical differential routing |
| 13, 15 | VPOS, GND | Positive supply and logic ground reference-GND serves as return for digital control and analog bias networks |
| 14, 16 | A1, A0 | Address inputs selecting active channel pair (00→CH1, 01→CH2, 10→CH3, 11→CH4)-TTL/CMOS compatible |
| 15 (shared) | EN | Enable input; high = active, low = all switches open-prevents signal leakage during standby or power sequencing |

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 offers fault protection and ±15V rating | Better suited for industrial I/O modules where overvoltage robustness is prioritized over ultra-low glitch | Select ADG1409BRUZ when input fault tolerance or latch-up immunity is required; DG1209ETE+ preferred for lowest distortion in metrology-grade DAQ |
| TMUX1309RTER | Single-supply only (+1.8V to +5.5V), lower bandwidth (35MHz), but CMOS process enables lower cost and smaller WQFN-16 package | Ideal for portable consumer electronics and battery-powered sensors-not suitable for ±15V or high-bandwidth use cases | Choose TMUX1309RTER for cost-sensitive, low-voltage portable designs; DG1209ETE+ remains optimal for high-fidelity, wide-supply industrial test systems |
Compared with ADG1409BRUZ and TMUX1309RTER, the DG1209ETE+ uniquely balances ultra-low charge injection (0.5pC), 250MHz bandwidth, and full ±15V bipolar compatibility-making it the only option among the three qualified for simultaneous high-speed, high-precision, and wide-dynamic-range analog multiplexing.

FAQ
What is the maximum operating voltage for DG1209ETE+ with bipolar supplies?
The DG1209ETE+ supports VPOS up to +20V and VNEG down to -20V, with absolute maximum ratings of VPOS to GND = -0.3V to +20.5V and VNEG to GND = -20.5V to +0.3V. For reliable operation, use within the specified ±15V range-exceeding this risks permanent damage and invalidates parametric guarantees. The DG1209ETE+ maintains full functionality and guaranteed specs across this bipolar range.
Does DG1209ETE+ support single-supply operation, and what are the constraints?
Yes, DG1209ETE+ operates with a +12V single supply (VPOS = +12V, VNEG = GND). In this mode, analog signals must stay within 0V to +12V, and RON increases to 165Ω typ. The device retains rail-to-rail capability and all key specs-including ≤1nA leakage and 0.5pC charge injection-remain valid across -40°C to +85°C. DG1209ETE+ does not support supplies below +10V in single-supply mode per datasheet min spec.
How does the dual-channel architecture of DG1209ETE+ differ from DG1208ETE+ in practical routing?
The DG1209ETE+ provides two fully independent 4:1 multiplexers (A-side and B-side), each with dedicated COM and NOx terminals-enabling true differential or parallel signal routing without shared paths. In contrast, DG1208ETE+ is a single 8:1 mux with one COM terminal. This makes DG1209ETE+ ideal for applications like differential ADC inputs or stereo audio switching, where channel pairing and isolation are mandatory. DG1209ETE+ uses only A1/A0 (not A2), simplifying control logic.
What is the role of the EN pin in DG1209ETE+, and can it be left floating?
The EN pin on DG1209ETE+ globally enables or disables all eight switches: high = active routing, low = all channels open (high-impedance state). It must never be left floating-uncontrolled EN states risk partial conduction, increased leakage, or undefined behavior. Tie EN to VPOS via pull-up or drive actively from a GPIO. DG1209ETE+ specifies VIH ≥2.4V and VIL ≤0.8V, ensuring compatibility with standard logic families without external conditioning.
Is thermal performance of DG1209ETE+ affected by PCB layout, and what is the recommended copper area?
Yes-thermal performance of DG1209ETE+ depends critically on PCB layout. Its 4mm × 4mm TQFN package includes an exposed pad (EP) that must be soldered to a minimum 25mm² internal or external copper pour connected to GND for optimal heat dissipation. With a 4-layer board, θJA drops to 40°C/W; inadequate copper raises junction temperature, degrading leakage current and RON stability. DG1209ETE+ datasheet specifies land pattern number 90-0070 for reliable thermal and mechanical mounting.
