Product details
Overview
DG412EUE+T from Maxim Integrated is a quad, normally open (NO), single-pole/single-throw (SPST) analog switch IC designed for precision signal routing in bipolar or single-supply systems. It features 45Ω max on-resistance at ±15V, <5nA off-leakage at +85°C, 100ns max tOFF, rail-to-rail analog signal handling (±15.5V), and TTL/CMOS logic compatibility - enabling use in battery-operated test equipment and military radio front-ends.
For engineers reviewing the DG412EUE+T datasheet, DG412EUE+T pinout, DG412EUE+T application, or DG412EUE+T equivalent, key selection criteria include guaranteed on-resistance flatness (Δ4Ω), low charge injection (10pC max), ESD tolerance (2000V min), and operation across -40°C to +85°C industrial temperature range.
Technical Context
The DG412EUE+T implements four independent SPST switches with NO configuration, controlled by separate digital inputs (IN1–IN4). Each switch conducts bidirectionally with matched on-resistance (≤3Ω difference between channels) and flat on-resistance profile (ΔRDS(ON) ≤4Ω) over its full ±15.5V analog signal range under bipolar supply conditions.
It operates from dual supplies (±4.5V to ±20V) or single supply (+10V to +30V), with VL pin configurable for TTL (5V) or CMOS (tied to V+) logic interface. Internal silicon-gate 44V process ensures robustness against overvoltage transients and supports rail-to-rail switching without signal clipping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RDS(ON)) | 45Ω max at ±15V - ensures minimal signal attenuation and voltage drop in precision analog paths |
| On-Resistance Flatness (ΔRDS(ON)) | Δ4Ω max - maintains consistent gain and linearity across full analog input range (±15.5V) |
| Off-Leakage Current | <5nA at +85°C - preserves signal integrity in high-impedance sample-and-hold and sensor interfaces |
| Turn-Off Time (tOFF) | 100ns max - enables fast channel switching in time-critical communication and test systems |
| Charge Injection | 10pC max - minimizes voltage glitch during switching in integrator and ADC input stages |
| ESD Tolerance | 2000V min per Method 3015.7 - provides built-in protection for handling and board-level reliability |
| Analog Signal Range | ±15.5V - supports full rail-to-rail operation with ±16.5V supplies, ideal for wide-dynamic-range instrumentation |
Pinout & Package
DG412EUE+T is housed in a 16-pin TSSOP package (U16-2), 4.4mm × 5.0mm body, 0.65mm pitch, with exposed pad not present (non-QFN variant). Pin 1 is IN1; pins 2–4 and 6–8 are D1–D4 and S1–S4 respectively; pins 11 and 13 are V+ and V−; pin 5 is GND; pin 10 is VL; pin 12 is S2; pin 9 is S3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 15,14,6,7) | Digital control inputs | TTL/CMOS-compatible logic signals enabling individual NO switch closure |
| D1–D4 (Pins 16,13,5,8) | Drain terminals | Analog current sink nodes - bidirectional conduction path when switch is ON |
| S1–S4 (Pins 1,11,12,9) | Source terminals | Analog current source nodes - completes signal path with Dx during ON state |
| V+ (Pin 13) | Positive supply rail | Connects to substrate; supports +10V to +30V single or +4.5V to +20V bipolar operation |
| V− (Pin 2) | Negative supply rail | Required for bipolar operation; enables ±4.5V to ±20V supply range and rail-to-rail analog swing |
| GND (Pin 3) | Reference ground | Logic and substrate reference; must be tied to system ground for stable digital interface |
| VL (Pin 10) | Logic supply voltage | Configures input threshold: 5V for TTL, V+ for CMOS - defines valid logic-high/low levels |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPST NO configuration | Four independent, non-latching switches - simplifies discrete multiplexer design and eliminates cross-talk risk of shared control |
| Guaranteed RDS(ON) matching | ≤3Ω max difference between any two channels - critical for balanced differential signal routing and calibration accuracy |
| Rail-to-rail analog handling | Supports ±15.5V signal swing with ±16.5V supplies - enables direct interfacing with op-amps and DACs without level-shifting |
| Low power consumption | 35µW max total supply current - extends battery life in portable test gear and handheld radios |
| Bipolar or single-supply operation | +10V to +30V or ±4.5V to ±20V - offers flexibility in legacy industrial systems and new low-voltage designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | Lower RDS(ON) (1.3Ω typ), but requires ≥±5V dual supply; no single-supply support below +12V | Better for low-distortion audio routing; unsuitable for +10V-only systems | Select ADG1412BRUZ only if supply headroom allows ≥±5V and on-resistance <2Ω is mandatory |
| TS5A23157DCUR | Single-supply only (+1.65V to +5.5V); 0.9Ω RDS(ON); limited to 5.5V analog range | Optimized for low-voltage portable electronics; cannot handle ±15V signals | Choose TS5A23157DCUR for battery-powered microcontrollers interfacing with 3.3V sensors - not for industrial signal conditioning |
Compared with DG412EUE+T, ADG1412BRUZ delivers superior on-resistance flatness and lower leakage but lacks single-supply flexibility, while TS5A23157DCUR offers ultra-low voltage operation yet sacrifices analog range and temperature rating - making DG412EUE+T the optimal choice for wide-range, industrial-grade signal routing where supply versatility and ruggedness are essential.

FAQ
What is the operating temperature range for DG412EUE+T?
The DG412EUE+T is rated for operation from -40°C to +85°C, making it suitable for industrial and extended-temperature applications. This rating is confirmed in the Ordering Information table and applies specifically to the "E" grade suffix in the part number DG412EUE+T. The device undergoes 100% testing at maximum hot temperature for leakage parameters, ensuring compliance across the full range.
Does DG412EUE+T support single-supply operation?
Yes, DG412EUE+T supports single-supply operation from +10V to +30V, with V− tied to ground. In this mode, the analog signal range is 0V to V+ − 0.5V (e.g., 0V to 11.5V at +12V supply). The datasheet specifies electrical characteristics for both single- and dual-supply configurations, including RDS(ON) = 100Ω max at +12V, confirming functional compatibility.
What is the pin configuration of DG412EUE+T?
DG412EUE+T uses a 16-pin TSSOP package (U16-2) with standard pinout: Pin 1 = S1, Pin 2 = V−, Pin 3 = GND, Pin 4 = S4, Pin 5 = D4, Pin 6 = IN4, Pin 7 = IN3, Pin 8 = D3, Pin 9 = S3, Pin 10 = VL, Pin 11 = V+, Pin 12 = S2, Pin 13 = D2, Pin 14 = IN2, Pin 15 = IN1, Pin 16 = D1. This matches the DG412 top-view diagram in the datasheet.
How does DG412EUE+T differ from DG411EUE+T?
DG412EUE+T is normally open (NO), while DG411EUE+T is normally closed (NC). Both share identical package, temperature grade, and core specifications (RDS(ON), leakage, timing), but their default logic states differ: DG412EUE+T connects Sx–Dx only when INx = HIGH, whereas DG411EUE+T disconnects them under the same condition. This functional distinction determines signal path default behavior in fail-safe designs.
Is DG412EUE+T pin-compatible with industry-standard DG412 variants?
Yes, DG412EUE+T is a plug-in upgrade for industry-standard DG412 devices, retaining identical pinout, footprint, and logic interface across DIP, SO, TSSOP, and QFN packages. The "E" grade confirms -40°C to +85°C operation, and all electrical timing, leakage, and resistance specs meet or exceed legacy DG412 requirements - enabling drop-in replacement without PCB changes.
