Product details
Overview
DG212ETE+T from Maxim Integrated is a quad SPST normally open analog switch designed for bidirectional signal routing in ±4.5V to ±18V dual-supply systems. It features 175Ω typical RDS(ON), <5pF OFF-capacitance per channel, guaranteed break-before-make switching, and operates across –40°C to +85°C. It is used in programmable gain amplifiers and automatic test equipment where rail-to-rail analog signal integrity is required.
For engineers reviewing the DG212ETE+T datasheet, DG212ETE+T pinout, DG212ETE+T application, or DG212ETE+T equivalent, key selection criteria include its no-VL-supply architecture, latch-up immunity during hot-insertion, low charge injection (20pC), and compatibility with TTL/CMOS logic levels without external level shifting.
Technical Context
The DG212ETE+T implements four independent CMOS transmission gates with inverted control logic relative to DG201/DG211. Each switch guarantees break-before-make timing and maintains near-constant on-resistance over the full ±15V analog signal range.
It eliminates the VL logic supply required by legacy equivalents while retaining full pin compatibility with industry-standard 16-pin SO, TSSOP, QFN, and Thin QFN footprints. Its monolithic CMOS design ensures sub-µA quiescent current and nonlatching behavior even when power supplies are disconnected while analog signals remain present.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - supports rail-to-rail signal switching without clipping in ±15V systems |
| RDS(ON) | 175Ω max at ±10V - ensures minimal insertion loss and voltage drop in precision signal paths |
| OFF-Leakage Current | ±5nA max at ±14V - preserves accuracy in high-impedance sample/hold and sensor interfaces |
| Switching Time (tON/tOFF) | 460ns / 450ns max - enables reliable operation in 1MHz multiplexing and data acquisition |
| OFF-Isolation | 70dB min at 100kHz - suppresses crosstalk between channels in multi-channel analog routing |
| Charge Injection | 20pC max - minimizes voltage glitch in sample-and-hold circuits and DAC output buffering |
| Supply Range | ±4.5V to ±18V continuous - allows flexible system-level power architecture without auxiliary regulators |
Pinout & Package
Package: 16-pin Thin QFN (3mm × 3mm, 0.5mm pitch) with exposed pad (EP); EP may be connected to V+ or left unconnected per layout requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 6, 7, 14, 15) | Inverted digital control inputs | Logic LOW activates corresponding switch; compatible with 0V/3.3V/5V TTL/CMOS drivers |
| D1–D4 (Pins 5, 8, 13, 16) | Analog drain terminals | Bidirectional signal path endpoints; tolerate ±15V and support current flow in either direction |
| S1–S4 (Pins 4, 3, 12, 11) | Analog source terminals | Paired with D1–D4 to form four independent SPST switches; no polarity dependency |
| V+ (Pin 11) | Positive supply input | Connects to substrate; must be ≥ |V−| and ≤ +25V relative to GND |
| V− (Pin 4) | Negative supply input | Supports negative rail down to –25V; enables true bipolar analog signal handling |
| GND (Pin 5) | Reference ground | Signal reference point; not tied to substrate; separate from power return paths |
| N.C. (Pin 10) | No connection | Internally unconnected; must be left floating or grounded per PCB layout best practices |
Key Features
| Feature | Design Value |
|---|---|
| No VL logic supply required | Eliminates third power rail, reducing BOM count and layout complexity vs. legacy DG212 variants |
| Guaranteed break-before-make | Prevents momentary short-circuit between analog channels during state transitions |
| Nonlatching under hot-insertion | Remains functional and damage-free when analog signals are present during power-down |
| Constant RDS(ON) over signal range | Minimizes THD and distortion in audio, instrumentation, and precision ADC front-ends |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Lower RDS(ON) (60Ω typ), but limited to ±5.5V supply; requires VL supply | Not suitable for ±15V systems; better for low-voltage portable instrumentation | Select DG212ETE+T when bipolar ±15V operation and no-VL simplicity are required |
| ADG1412BRUZ | Higher performance: 1.8Ω RDS(ON), 0.2pC charge injection, but ±15V operation requires external level shifters | Demands additional logic interface circuitry; higher cost and board area | Choose DG212ETE+T for drop-in replacement in existing ±15V designs without layout changes |
Compared with MAX4617ESE+ and ADG1412BRUZ, the DG212ETE+T uniquely balances wide supply range (±4.5V to ±18V), no-VL operation, and robust hot-swap tolerance-making it optimal for industrial test, telecom, and legacy-compatible analog routing where reliability and supply flexibility outweigh ultra-low RDS(ON).

FAQ
What is the operating temperature range for DG212ETE+T?
The DG212ETE+T is rated for –40°C to +85°C operation, matching the DG212E grade specification. This extended industrial temperature range ensures reliable performance in demanding environments such as automated test equipment enclosures and telecom line cards where ambient temperatures exceed commercial-grade limits. The DG212ETE+T maintains full electrical specifications-including RDS(ON), leakage, and switching times-across this entire range.
Does DG212ETE+T require a VL logic supply voltage?
No, the DG212ETE+T does not require a VL logic supply. Unlike earlier DG212 variants and competing analog switches, Maxim eliminated the VL pin while preserving full TTL/CMOS logic compatibility across 0V to 5V input levels. This simplifies power delivery and reduces PCB layer count. The DG212ETE+T accepts standard logic signals directly at its IN1–IN4 pins without level translation or auxiliary rails.
How does DG212ETE+T handle power-off conditions with live analog signals?
The DG212ETE+T is explicitly designed to remain nonlatching when power supplies are removed while analog signals remain present-a condition known as hot-insertion or signal-first startup. Internal protection structures prevent parasitic SCR activation, ensuring safe operation in systems like modular instrumentation or field-replaceable units. This behavior is guaranteed per Maxim's datasheet Absolute Maximum Ratings and Electrical Characteristics tables.
What is the maximum analog signal voltage supported by DG212ETE+T?
The DG212ETE+T supports an analog signal range of ±15V, meaning it can pass signals from –15V to +15V without distortion or clipping when operated with ±15V supplies. Its absolute maximum ratings allow VS and VD to swing from V− to V+, so with ±18V supplies, the usable analog range extends to ±18V. This makes the DG212ETE+T suitable for industrial process control and high-dynamic-range sensor interfaces.
Is DG212ETE+T pin-compatible with other DG212 package variants?
Yes, the DG212ETE+T uses the same 16-pin Thin QFN footprint as other DG212E-grade variants (e.g., DG212EUE, DG212EGE), sharing identical pin numbering, function mapping, and thermal pad configuration. Its pinout matches the industry-standard 16-pin SO and TSSOP layouts electrically-though mechanical adaptation is required for package interchange. All DG212 variants share identical logic behavior, timing, and electrical specs within their respective temperature grades.
