Product details
Overview
DG412EUE+ 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+ datasheet, DG412EUE+ pinout, DG412EUE+ application, or DG412EUE+ equivalent, key selection criteria include guaranteed on-resistance matching (≤3Ω), low charge injection (≤10pC), ESD tolerance (≥2000V), and operation across -40°C to +85°C industrial temperature range with TSSOP-16 packaging.
Technical Context
The DG412EUE+ implements four independent SPST switches with NO configuration, each controlled by a dedicated digital input (IN1–IN4). Its silicon-gate 44V process enables robust ±4.5V to ±20V bipolar or +10V to +30V single-supply operation, with VL pin supporting 5V logic level translation.
Switching is bidirectional with symmetrical on-resistance flatness (ΔRDS(ON) ≤ 4Ω over full analog range) and guaranteed channel-to-channel RDS(ON) match (≤3Ω). Off-isolation exceeds 68dB and crosstalk remains below 85dB at 1MHz, critical for high-fidelity audio and sample-and-hold circuits.
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 Match | 3Ω max between channels - maintains consistent gain/attenuation across multi-channel routing |
| Off-Leakage Current | <5nA at +85°C - preserves accuracy in high-impedance sample-and-hold and sensor interfaces |
| Charge Injection | 10pC max - minimizes voltage glitch during switching in integrator and ADC front-end applications |
| Turn-Off Time (tOFF) | 100ns max - supports fast multiplexing in real-time communication and test instrumentation |
| Analog Signal Range | ±15.5V at ±16.5V supplies - enables full rail-to-rail signal handling without clipping |
| ESD Tolerance | 2000V min per Method 3015.7 - provides robust handling during board assembly and field service |
Pinout & Package
DG412EUE+ uses a 16-pin TSSOP package (U16-2, JEDEC MO-153) with exposed pad not connected internally - standard mounting requires soldering pad to ground or V+ per layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 15, 14, 7, 6) | Digital control inputs | TTL/CMOS-compatible logic signals enabling individual SPST switch closure (NO type) |
| D1–D4 (Pins 16, 13, 10, 5) | Analog drain terminals | High-impedance side of switch; connects to signal source or load depending on routing topology |
| S1–S4 (Pins 1, 3, 12, 4) | Analog source terminals | Low-impedance side tied to common reference or output node; bidirectional conduction supported |
| V+ (Pin 11) | Positive supply | Connects to +10V to +30V (single) or positive rail of bipolar supply; also substrate connection |
| V- (Pin 2) | Negative supply | Connects to 0V (single) or -4.5V to -20V (bipolar); clamped diodes protect against overvoltage |
| GND (Pin 3) | Ground reference | Logic and analog return path; separate from power supply grounds in mixed-signal layouts |
| VL (Pin 10) | Logic supply | Accepts 5V for TTL compatibility or ties to V+ for CMOS-level inputs; defines logic threshold |
Key Features
| Feature | Design Value |
|---|---|
| Plug-in upgrade for legacy DG412 | Pin- and function-compatible replacement with improved RDS(ON) match and leakage performance |
| Rail-to-rail signal handling | Supports analog signals from V- to V+ without distortion - essential for ±15V op-amp interfaces |
| Low power consumption | 35µW max total supply current - extends battery life in portable test and comms equipment |
| Bidirectional conduction | Identical on-resistance regardless of signal direction - simplifies PCB layout and signal flow design |
| Guaranteed flatness over signal range | ΔRDS(ON) ≤ 4Ω across full ±15.5V range - maintains linearity in precision measurement paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | 40Ω RDS(ON) typical at ±15V; 16-TSSOP; 100k-cycle lifetime rating | Higher cost; better RDS(ON) flatness (±0.5Ω) but higher charge injection (12pC) | Preferred where lower on-resistance variation is critical, but DG412EUE+ offers better ESD rating (2000V vs. 1000V HBM) |
| TS5A3157DCUR | Single-channel, 0.9Ω RDS(ON) at 3.3V; 6-pin SC70; not pin-compatible | Designed for low-voltage portable gear only; lacks bipolar support and temperature range | Only suitable for new low-voltage designs; DG412EUE+ remains optimal for industrial/military bipolar systems |
Compared with ADG1412BRUZ and TS5A3157DCUR, DG412EUE+ uniquely balances wide supply range (±4.5V to ±20V), industrial temperature rating (-40°C to +85°C), and proven ESD robustness - making it the preferred choice for ruggedized analog routing where reliability trumps marginal RDS(ON) improvement.

FAQ
What is the maximum allowable supply voltage for DG412EUE+?
The DG412EUE+ supports absolute maximum ratings of V+ = 44V and V- = (GND − 0.3V) to (V+ + 0.3V). For continuous operation, the recommended dual-supply range is ±4.5V to ±20V, or single-supply +10V to +30V. Exceeding these ranges risks permanent damage, as internal clamping diodes limit forward current to 30mA.
Does DG412EUE+ support rail-to-rail analog signal switching?
Yes, DG412EUE+ supports rail-to-rail analog signal handling up to ±15.5V when operated at ±16.5V supplies. This capability is confirmed in the Electrical Characteristics table under "Analog Signal Range" and validated across temperature, enabling direct interfacing with ±15V op-amps and data converters without level-shifting circuitry.
What is the logic configuration of DG412EUE+ switches?
DG412EUE+ implements four normally open (NO) SPST analog switches. When INx = 0V (logic low), the corresponding switch is open (high impedance); when INx = 2.4V (logic high), the switch closes (low RDS(ON)). This behavior is explicitly defined in the Functional Diagrams section and matches the DG412 designation in the ordering table.
How does DG412EUE+ differ from the older DG412CUE?
DG412EUE+ replaces DG412CUE with enhanced specifications: improved RDS(ON) matching (≤3Ω vs. unspecified), guaranteed RFLAT(ON) (≤4Ω), lower off-leakage (<5nA at +85°C vs. <10nA), and higher ESD tolerance (2000V vs. unspecified). Both share identical pinout, package (TSSOP-16), and temperature range (-40°C to +85°C), making DG412EUE+ a direct drop-in upgrade.
Can DG412EUE+ operate from an unbalanced supply such as +24V and -5V?
Yes, DG412EUE+ supports unbalanced supplies - the datasheet explicitly states operation with configurations like +24V and -5V, provided the difference between V+ and V- does not exceed +44V. In such cases, VL must be set to 5V for TTL compatibility or tied to V+ for CMOS logic levels, and analog signal range adjusts accordingly.
