Product details
Overview
DG411AK-E3 from Vishay Siliconix is a precision monolithic quad SPST CMOS analog switch designed for high-speed, low-error signal routing in dual-supply systems. It features 25 Ω on-resistance, 110 ns turn-on time, ±15 V analog signal range, and operates across –55°C to +125°C. It is used in precision data acquisition systems requiring break-before-make switching and ultra-low charge injection.
For engineers reviewing the DG411AK-E3 datasheet, DG411AK-E3 pinout, DG411AK-E3 application, or DG411AK-E3 equivalent, key selection criteria include guaranteed rDS(on) ≤ 45 Ω over temperature, 44 V max supply rating, TTL/CMOS-compatible control logic, and LCC-20 ceramic package suitability for high-reliability military and aerospace deployments.
Technical Context
The DG411AK-E3 implements four independent bidirectional SPST switches fabricated using Vishay's high-voltage silicon gate process with epitaxial latchup protection. Each switch supports rail-to-rail analog signal conduction (±15 V) and blocks up to ±44 V supply differential, with digital control referenced to VL (logic supply) and compatible with 0.8 V / 2.4 V TTL thresholds.
It employs break-before-make switching action and delivers 5 pC typical charge injection - critical for sample-and-hold and multiplexed ADC front-ends. The device supports both dual-supply (±15 V) and single-supply (12 V) operation, with guaranteed performance across its full military temperature range (–55°C to +125°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full-rail signal switching without clipping in bipolar instrumentation circuits |
| rDS(on) Max | 45 Ω at –55°C to +125°C - ensures minimal gain error and THD degradation in precision amplifiers |
| tON / tOFF | 240 ns / 160 ns max - enables >1 MHz multiplexing in high-speed data loggers |
| Charge Injection | 5 pC typical - limits voltage step error in capacitor-coupled sample-and-hold stages |
| Off Isolation (OIRR) | 68 dB at 1 MHz - suppresses crosstalk between adjacent channels in multi-channel DAQ |
| Supply Voltage Range | V+ to V– = 44 V max - allows operation with ±20 V supplies or 40 V single-ended rails |
| Logic Supply (VL) | (GND –0.3 V) to (V+) +0.3 V - enables direct interface with 3.3 V or 5 V microcontrollers |
Pinout & Package
Package: 20-lead LCC (Leadless Chip Carrier), hermetically sealed ceramic, suitable for high-reliability and extended-temperature applications. Pin 1 identified by dot; no leads protrude - surface-mount only with solder reflow profile per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | IN1–IN4 | Digital control inputs - active-low logic for DG411 ('0' = ON); referenced to VL |
| 5, 6, 16, 17 | S1–S4 | Switch source terminals - bidirectional analog inputs/outputs; connect to signal sources |
| 7, 8, 15, 14 | D1–D4 | Switch drain terminals - bidirectional analog inputs/outputs; connect to loads or downstream circuitry |
| 9 | V– | Negative supply rail - must be connected to system negative reference (e.g., –15 V) |
| 10 | V+ | Positive supply rail - connects to system positive reference (e.g., +15 V) |
| 11 | GND | Analog ground reference - separate from digital ground; ties internal substrate bias |
| 12 | VL | Logic supply input - sets logic threshold; typically tied to +5 V or +3.3 V |
| 13, 18, 19, 20 | NC | No-connect pins - internally unconnected; must remain floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG411BRZ | 44 V supply rating, 35 Ω rDS(on), –40°C to +85°C grade only; SOIC-16 package | Lacks military temperature range and LCC-20 hermetic sealing; not suitable for aerospace deployment | Select when commercial-grade performance and PCB space constraints favor SOIC-16 mounting |
| MAX4611ESE+ | 36 V supply rating, 35 Ω rDS(on), –40°C to +85°C; enhanced ESD protection (±4 kV HBM) | Higher leakage (±20 nA vs. ±5 nA) and no extended temp option; optimized for industrial PLC I/O modules | Select when robustness against field ESD events outweighs need for extended temperature operation |

FAQ
What is the maximum supply voltage rating for DG411AK-E3?
The DG411AK-E3 supports a maximum V+ to V– differential of 44 V, with absolute maximum ratings of GND to V– = 25 V and VL = (GND –0.3 V) to (V+) +0.3 V. This allows safe operation with ±20 V supplies or 40 V single-ended rails, verified per Vishay S-52433 Rev. D specifications.
Does DG411AK-E3 support single-supply operation?
Yes, DG411AK-E3 supports single-supply operation from 5 V to 44 V. In this mode, V+ is tied to VL and V– is connected to ground. Performance is characterized at 12 V, and the Input Switching Threshold vs. Supply Voltage curve confirms functional logic levels across the full unipolar range.
What is the guaranteed on-resistance specification for DG411AK-E3 over temperature?
The DG411AK-E3 guarantees rDS(on) ≤ 45 Ω across its full operating temperature range of –55°C to +125°C, measured at V+ = 13.5 V, V– = –13.5 V, IS = –10 mA, and VD = 8.5 V - a key parameter for minimizing gain error in precision amplifier interfaces.
Is DG411AK-E3 pin-compatible with other variants in the DG411 family?
Yes, DG411AK-E3 shares identical pinout and footprint with all DG411-series LCC-20 variants (e.g., DG411AZ/883), including matching INx, Sx, Dx, V+, V–, GND, VL, and NC assignments. This enables drop-in replacement within the same package type without PCB modification.
What logic polarity does DG411AK-E3 implement?
DG411AK-E3 implements active-low control logic: a logic '0' (≤0.8 V) turns the switch ON, and a logic '1' (≥2.4 V) turns it OFF. This is confirmed in the Truth Table of Vishay S-52433 Rev. D and distinguishes it from DG412 (active-high) and DG413 (mixed NO/NC).
