Product details
Overview
DG412EGE from Maxim Integrated is a quad, normally open (NO), single-pole/single-throw (SPST) analog switch optimized for bidirectional signal routing in precision analog systems. It features 35Ω max on-resistance, <5nA off-leakage at +85°C, 10pC max charge injection, rail-to-rail analog signal handling (±15V), and TTL/CMOS logic compatibility - enabling use in sample-and-hold circuits, audio routing, and battery-operated test equipment.
For engineers reviewing the DG412EGE datasheet, DG412EGE pinout, DG412EGE application, or DG412EGE equivalent, key selection criteria include guaranteed on-resistance flatness (Δ4Ω max), low interchannel RDS(ON) mismatch (3Ω max), ESD tolerance (2000V min), and operation across ±4.5V to ±20V or +10V to +30V supplies.
Technical Context
The DG412EGE implements four independent SPST switches with NO configuration, each controlled by a dedicated digital input (IN1–IN4). Its silicon-gate 44V process enables robust bipolar and single-supply operation while maintaining low leakage and high off-isolation (68dB).
Switching is fully bidirectional with symmetrical on-resistance and capacitance (CD(OFF) = CS(OFF) = 9pF), and timing is characterized with tON ≤ 145ns and tOFF ≤ 100ns under ±15V conditions. Charge injection is tightly controlled (≤10pC) to minimize sampling error in precision acquisition paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally open (NO) - all four channels open when logic input is low. |
| RDS(ON) Max | 35Ω at ±15V - ensures minimal signal attenuation and distortion in audio and instrumentation paths. |
| RFLAT(ON) | Δ4Ω max over full analog range - guarantees consistent gain and linearity across input voltage swing. |
| Off-Leakage Current | <5nA at +85°C - preserves accuracy in high-impedance sample-and-hold and sensor interfaces. |
| Charge Injection | 10pC max - limits voltage glitch on hold capacitors, critical for 12-bit+ data acquisition stability. |
| Supply Range | ±4.5V to ±20V bipolar or +10V to +30V single supply - supports industrial and military-grade voltage margins. |
| ESD Rating | 2000V min per Method 3015.7 - enhances reliability in handling and board-level assembly environments. |
Pinout & Package
Package: 16-pin QFN with exposed paddle (EP); EP must be connected to V+ for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control inputs | TTL/CMOS-compatible logic signals; low = switch open (NO), high = switch closed. |
| D1–D4 | Analog drain terminals | High-impedance side of switch; connects to load or downstream circuitry. |
| S1–S4 | Analog source terminals | Low-impedance side; typically tied to signal source or common reference point. |
| V+ | Positive supply rail | Must be ≥ |V−| + 1V; substrate connection point - ties to EP in QFN package. |
| V− | Negative supply rail | Required for bipolar operation; sets lower bound of analog signal range. |
| GND | Analog/digital ground reference | Common return for logic and analog sections; separate from V− in bipolar mode. |
| VL | Logic supply voltage | Set to +5V for TTL compatibility or to V+ for CMOS-level inputs. |
Key Features
| Feature | Design Value |
|---|---|
| RDS(ON) matching | 3Ω max between channels - eliminates gain mismatch in multi-channel signal routing or multiplexing. |
| Rail-to-rail analog handling | ±15V signal range with ±15V supplies - enables full dynamic range utilization without clipping. |
| Low power consumption | 35µW max - extends battery life in portable test and measurement instruments. |
| Break-before-make timing | 25ns (DG413 only; not applicable to DG412EGE) - excluded; DG412EGE is SPST NO with no break-before-make requirement. |
| Off-isolation | 68dB at 1MHz - suppresses crosstalk between active and inactive channels in dense PCB layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | 4-channel SPST NO, 1.8Ω RDS(ON), but requires ±15V or +12V single supply only; no ±4.5V min support. | Better on-resistance for low-distortion audio, but narrower supply flexibility limits use in wide-input-range test gear. | Select ADG1412BRUZ when ultra-low RDS(ON) is critical and supply rails are fixed at ±15V/+12V. |
| TS5A23157DCUR | Single-supply only (1.65V–5.5V), 0.9Ω RDS(ON), but max analog range limited to VCC – 0.2V; no bipolar capability. | Optimized for low-voltage portable electronics, not compatible with ±15V signal conditioning or industrial test systems. | Choose TS5A23157DCUR for battery-powered 3.3V/5V systems where rail-to-rail analog swing is unnecessary. |
Compared with ADG1412BRUZ and TS5A23157DCUR, the DG412EGE uniquely supports both wide bipolar (±4.5V to ±20V) and high-voltage single-supply (up to +30V) operation while delivering guaranteed on-resistance flatness and sub-5nA leakage at +85°C - making it the only option among the three qualified for precision, high-voltage, temperature-stable analog routing.

FAQ
What is the operating temperature range for the DG412EGE?
The DG412EGE is rated for operation from -40°C to +85°C, as confirmed in the Ordering Information table. This extended industrial temperature grade ensures reliable performance in harsh environments such as factory automation test rigs, outdoor communication systems, and avionics subsystems - unlike the commercial-grade DG412Cxx variants limited to 0°C to +70°C.
Does the DG412EGE support single-supply operation?
Yes, the DG412EGE supports single-supply operation from +10V to +30V, with V− connected to ground. The datasheet explicitly states this capability in both the General Description and Electrical Characteristics sections, and specifies analog signal range (0V to V+) and performance parameters under +12V single-supply conditions.
What is the maximum analog signal voltage the DG412EGE can handle?
The DG412EGE supports rail-to-rail analog signals up to ±15.5V when operated with ±16.5V supplies, and up to 12V with a +12V single supply. Absolute maximum ratings confirm V+ up to 44V and analog inputs (S/D) clamped to V+ and V−, enabling safe handling of signals spanning the full supply rails.
Is the exposed paddle (EP) on the DG412EGE QFN package required to be connected?
Yes - the exposed paddle (EP) on the DG412EGE QFN package must be connected to V+, as stated in the Pin Description table and Package Information section. This connection provides essential thermal conduction and substrate biasing; leaving EP floating or grounding it degrades on-resistance, leakage, and ESD performance.
How does the DG412EGE differ from the DG411EGE and DG413EGE?
The DG412EGE is a normally open (NO) quad SPST switch, whereas DG411EGE is normally closed (NC) and DG413EGE integrates two NC and two NO switches. All share identical electrical specs (RDS(ON), leakage, charge injection), but their logic polarity and default state differ - making DG412EGE ideal for safety-critical "open-by-default" signal gating applications.
