Product details
Overview
DG417LEUA+ from Maxim Integrated is a precision CMOS single-pole/single-throw (SPST) analog switch with normally closed (NC) configuration, 35Ω maximum on-resistance, ±4.5V to ±20V dual-supply or +9V to +36V single-supply operation, and +3V logic-compatible digital inputs (VIH = 2.0V, VIL = 0.8V). It delivers rail-to-rail analog signal handling, <5nA off-leakage at +85°C, and sub-175ns turn-on time-ideal for battery-operated test equipment and audio routing where low distortion and minimal charge injection are critical.
For engineers reviewing the DG417LEUA+ datasheet, DG417LEUA+ pinout, DG417LEUA+ application, or DG417LEUA+ equivalent, key selection considerations include its NC topology, guaranteed RON matching (≤3Ω), RON flatness (≤4Ω), extended -40°C to +85°C temperature rating, and µMAX-8 package compatibility with space-constrained industrial and communications systems.
Technical Context
The DG417LEUA+ implements a fully complementary CMOS transmission-gate architecture enabling bidirectional conduction, zero power-supply sequencing requirements, and latchup immunity across its full supply range. Its digital input stage features fixed TTL/CMOS thresholds independent of supply voltage, verified over ±4.5V to ±20V and +9V to +36V conditions.
Signal integrity is maintained via low charge injection (15pC typical), high off-isolation (-90dB at 1MHz), and low THD (0.002% at 20Hz–20kHz), all specified and tested across the full -40°C to +85°C operating range with guaranteed limits-not just typical values.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 35Ω max at ±15V supplies - ensures minimal signal attenuation and gain error in precision signal paths |
| RON matching | 3Ω max between channels - enables matched gain/attenuation in differential or dual-path circuits |
| RON flatness | 4Ω max over full signal range - preserves linearity in audio, instrumentation, and sample-and-hold applications |
| Off-leakage current | <5nA at +85°C - prevents DC error accumulation in high-impedance, long-integration-time circuits |
| Turn-on time (tON) | 175ns max - supports fast multiplexing in automated test equipment and real-time control loops |
| Logic compatibility | +3V TTL/CMOS (VIH = 2.0V, VIL = 0.8V) - interfaces directly with microcontrollers and FPGAs without level-shifting |
| Supply range | ±4.5V to ±20V dual or +9V to +36V single - simplifies system power architecture in mixed-signal industrial designs |
Pinout & Package
Package: 8-pin µMAX (3mm × 3mm, 0.5mm pitch), thermally enhanced, lead-free, RoHS-compliant surface-mount package rated for -40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 COM | Analog common terminal | Primary signal path node; connects to load or source in NC configuration; bidirectional conduction |
| 2 N.C. | No connection | Internally unconnected; must remain floating or grounded per layout best practices to avoid noise coupling |
| 3 GND | Digital logic ground reference | Reference for IN logic input; separate from analog supply grounds but requires low-impedance connection |
| 4 V+ | Analog positive supply | Bias for internal CMOS switches; sets upper rail for rail-to-rail analog signal handling |
| 6 IN | Logic control input | Active-low logic sense: logic low closes switch (COM ↔ NC); logic high opens switch |
| 7 V- | Analog negative supply | Bias for internal CMOS switches; sets lower rail; enables bipolar signal switching down to -15V |
| 8 NC | Normally closed analog terminal | Closed to COM when IN = low; open when IN = high; carries full analog signal current up to ±30mA continuous |
Key Features
| Feature | Design Value |
|---|---|
| +3V logic compatibility | Fixed VIH = 2.0V / VIL = 0.8V thresholds ensure reliable interface with 3.3V microcontrollers without external biasing |
| Power-supply sequencing freedom | No required startup order for V+, V-, or GND - eliminates risk of latchup and simplifies power management design |
| Rail-to-rail analog handling | Supports signals from V- to V+ (e.g., -15V to +15V) - enables full dynamic range utilization in precision instrumentation |
| Low charge injection | 15pC typical - minimizes voltage glitch on sampled nodes in S/H circuits and ADC front-ends |
| Guaranteed RON flatness | 4Ω max variation across signal range - maintains consistent gain and phase response in audio and communication paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUA+ | SPST NO topology (not NC); 60Ω RON; +2.7V to +12V single-supply only; no dual-supply support | Suitable for low-voltage, single-rail systems where NC functionality is not required | Select when supply is limited to ≤12V and fail-open behavior is acceptable |
| ADG1419BRMZ | SPDT configuration (NC + NO); 1.3Ω RON; ±5V to ±22V dual-supply; higher cost; SOIC-10 package | Used where dual-path selection is needed, not simple NC switching | Choose only if SPDT function and ultra-low RON justify larger footprint and cost premium |
Compared with MAX4617EUA+ and ADG1419BRMZ, the DG417LEUA+ uniquely combines NC topology, guaranteed RON matching, dual-supply flexibility, and µMAX-8 packaging-making it irreplaceable in legacy-replacement, battery-powered, and bipolar-signal applications demanding fail-safe closure and thermal robustness.

FAQ
What is the logic polarity of the DG417LEUA+ control input?
The DG417LEUA+ features active-low logic control: when the IN pin is at logic low (≤0.8V), the switch is closed (COM connected to NC); when IN is at logic high (≥2.0V), the switch opens. This NC behavior provides fail-safe closure during power-down or controller reset, a critical feature in safety-critical analog paths. The DG417LEUA+ does not require pull-up or pull-down resistors on IN for proper operation under standard 3.3V logic drive.
Can the DG417LEUA+ operate from a single +12V supply?
Yes, the DG417LEUA+ supports single-supply operation from +9V to +36V. With V+ = +12V and V- tied to GND, it maintains rail-to-rail analog switching from 0V to +12V. RON increases to 125Ω max under these conditions (vs. 35Ω at ±15V), and leakage remains <5nA at +85°C. The logic thresholds (VIH = 2.0V, VIL = 0.8V) remain unchanged, ensuring compatibility with standard 3.3V or 5V controllers.
Does the DG417LEUA+ require power-supply sequencing?
No-the DG417LEUA+ eliminates power-supply sequencing requirements. Unlike earlier DG417 variants, it operates safely regardless of the order in which V+, V-, and GND are applied. This is achieved through internal circuitry that prevents latchup across the full ±4.5V to ±20V dual-supply or +9V to +36V single-supply range. Engineers can simplify power tree design and eliminate external protection diodes previously needed for legacy parts.
What is the maximum analog signal voltage the DG417LEUA+ can handle?
The DG417LEUA+ supports analog signals from V- to V+, with absolute maximum ratings of (V- − 0.3V) to (V+ + 0.3V) on COM, NC, and NO pins. For example, with V+ = +15V and V- = −15V, signals from −15.3V to +15.3V are permissible. Exceeding these clamps forward-biases internal ESD diodes; sustained current beyond ±30mA continuous or ±100mA pulsed risks damage. Always limit external signal sources accordingly.
Is the DG417LEUA+ pin-compatible with the original DG417?
Yes-the DG417LEUA+ is a direct pin-compatible upgrade for the DG417 in the 8-pin µMAX package. Pin functions, numbering, and physical dimensions match exactly. Key improvements include guaranteed RON matching (≤3Ω), tighter RON flatness (≤4Ω), lower leakage (<5nA at +85°C), and elimination of power-supply sequencing. No PCB or schematic changes are required when replacing DG417 with DG417LEUA+.
