Product details
Overview
DG417LEUA+T from Maxim Integrated is a precision CMOS single-pole/single-throw (SPST) analog switch with normally closed (NC) configuration, 35Ω max 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 sample-and-hold circuits and battery-operated communications systems.
For engineers reviewing the DG417LEUA+T datasheet, DG417LEUA+T pinout, DG417LEUA+T application, or DG417LEUA+T equivalent, key selection criteria include guaranteed RON matching (≤3Ω), RON flatness (≤4Ω), charge injection (15pC), off-isolation (–90dB at 1MHz), and µMAX-8 package compatibility in industrial temperature range (–40°C to +85°C).
Technical Context
The DG417LEUA+T implements a fully differential CMOS transmission gate architecture enabling bidirectional analog conduction with minimal distortion. Its logic interface eliminates power-supply sequencing requirements - V+, V−, and GND may power up in any order without latchup risk.
It supports both bipolar and single-ended supply configurations while maintaining guaranteed performance across –40°C to +85°C. Signal path design ensures rail-to-rail voltage handling (VCOM from V− to V+), low THD (0.002%), and high off-isolation, making it suitable for precision multiplexing in test equipment and audio routing.
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 - critical for matched gain/phase in differential or multi-channel sampling. |
| RON Flatness | ≤4Ω max over full signal range - preserves linearity across VCOM from V− to V+. |
| Off-Leakage Current | <5nA at +85°C - prevents DC error accumulation in high-impedance sample-and-hold nodes. |
| Turn-On/Off Time | <175ns / <185ns - enables fast switching in data acquisition and communication timing-critical applications. |
| Logic Thresholds | VIH = 2.0V, VIL = 0.8V - ensures reliable interfacing with +3V TTL and CMOS controllers without level-shifting. |
| Supply Range | ±4.5V to ±20V dual or +9V to +36V single - supports wide-range industrial and battery-backed systems. |
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 Switch Common Terminal | Signal path input/output shared by NC and NO paths; must remain within V− to V+ rails. |
| 2 N.C. | No Connection | Internally unconnected; no electrical function - leave floating or ground per layout best practice. |
| 3 GND | Logic Ground Reference | Reference for digital input thresholds; separate from analog ground but tied at system star point. |
| 4 V+ | Analog Positive Supply Input | Bias for P-channel MOSFETs; sets upper analog rail limit and powers internal logic bias network. |
| 6 IN | Logic-Level Control Input | Active-low control for DG417L: logic '0' closes COM–NC path; logic '1' opens switch. |
| 7 V− | Analog Negative Supply Input | Bias for N-channel MOSFETs; sets lower analog rail limit and completes analog switch biasing. |
| 8 NC | Normally Closed Analog Terminal | Default-conducting path to COM when IN = 0; breaks at IN = 1 - used for fail-safe or default-on signal routing. |
Key Features
| Feature | Design Value |
|---|---|
| +3V Logic Compatibility | VIH = 2.0V / VIL = 0.8V thresholds enable direct interface with 3.3V microcontrollers and FPGAs without level shifters. |
| Power-Supply Sequencing-Free Operation | No required power-up order for V+, V−, or GND - eliminates external diode protection and simplifies power management design. |
| Rail-to-Rail Analog Signal Handling | Supports VCOM from V− to V+ - preserves full dynamic range in ±15V op-amp stages or single-supply 0–36V sensor interfaces. |
| Low Charge Injection (15pC) | Minimizes voltage glitch on high-impedance hold capacitors - essential for 12-bit+ accuracy in sample-and-hold circuits. |
| Guaranteed Off-Isolation (–90dB) | Prevents crosstalk between active and inactive channels at 1MHz - critical in multi-channel test instrumentation and audio matrix routing. |
Applications
| Sample-and-Hold Circuits | Communications Systems |
|---|---|
Use Scenario: Precision acquisition of analog sensor outputs before ADC conversion in portable data loggers. IC Role / Device Role / Timing Role: Normally closed SPST switch isolating hold capacitor during sampling phase; opened only during acquisition window.

IC Role / Device Role / Timing Role: Low-quiescent-current analog switch enabling sleep-mode signal path preservation with <10µA total supply current. Use Value: Single-supply +9V to +36V operation accommodates battery voltage sag; <5nA leakage prevents standby current drain in multi-week deployments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUA+ | Lower RON (15Ω), higher supply current (150µA), same µMAX-8 package and –40°C to +85°C rating. | Better for low-distortion audio routing; less suitable for ultra-low-power battery systems due to higher ICC. | Select MAX4617EUA+ when RON and THD are prioritized over quiescent current. |
| ADG1419BRMZ | SPDT configuration, higher RON (18Ω typ), requires 5V logic interface, SOIC-10 package, –40°C to +125°C rating. | Designed for automotive-grade thermal robustness; incompatible pinout and logic voltage - not drop-in. | Choose ADG1419BRMZ only if extended temperature range and SPDT functionality are mandatory. |
Compared with DG417LEUA+T, MAX4617EUA+ offers superior on-resistance but higher static power, while ADG1419BRMZ provides wider temperature tolerance and SPDT topology at the cost of pinout redesign and logic-level mismatch - neither is pin-compatible, and both require schematic and layout revision.

FAQ
What is the maximum allowable analog signal voltage range for DG417LEUA+T?
The DG417LEUA+T supports rail-to-rail analog signal handling: VCOM, NC, and NO terminals operate from V− to V+ (e.g., –15V to +15V with ±15V supplies). Absolute maximum ratings specify (V− – 0.3V) to (V+ + 0.3V); exceeding this risks diode conduction and potential damage. Always ensure signal voltages stay within supply rails for guaranteed linear operation.
Does DG417LEUA+T require power-supply sequencing during startup?
No - DG417LEUA+T is explicitly designed for power-supply sequencing-free operation. Unlike legacy DG417 devices, it eliminates the need for strict V+, VL, then V− sequencing. V+, V−, and GND may power up in any order without latchup risk, simplifying power design and removing external protection diodes.
What is the logic polarity of DG417LEUA+T's control input?
DG417LEUA+T is a normally closed (NC) SPST switch: logic low (IN ≤ 0.8V) closes the COM–NC path; logic high (IN ≥ 2.0V) opens it. This active-low behavior is fixed per device function and matches the DG417L family designation - no configuration pins or mode registers exist.
Can DG417LEUA+T operate from a single +12V supply?
Yes - DG417LEUA+T supports single-supply operation from +9V to +36V. With +12V applied to V+, GND to V−, and logic referenced to GND, it delivers full functionality including rail-to-rail signal handling (0V to +12V), though RON increases to 125Ω max and leakage remains <5nA at +85°C per datasheet specifications.
Is DG417LEUA+T pin-compatible with the older DG417 series?
Yes - DG417LEUA+T maintains identical pinout, package dimensions, and electrical interface with the original DG417, DG418, and DG419 families. It is specified as a plug-in upgrade offering improved leakage, sequencing freedom, and tighter RON matching - no PCB or schematic changes are needed for migration.
