Product details
Overview
DG412AK-E3 from Vishay Siliconix is a precision monolithic quad SPST CMOS analog switch with break-before-make switching action, 25 Ω typical on-resistance (rDS(on)), 110 ns turn-on time (tON), and ±15 V analog signal range - used in high-accuracy data acquisition systems requiring low signal distortion and bidirectional conduction.
For engineers reviewing the DG412AK-E3 datasheet, DG412AK-E3 pinout, DG412AK-E3 application, or DG412AK-E3 equivalent, key selection criteria include its –55 °C to +125 °C operating temperature range, 16-pin CerDIP package, dual-supply (±15 V) or single-supply (up to 44 V) capability, and TTL/CMOS-compatible digital control inputs.
Technical Context
The DG412AK-E3 implements four independent SPST switches with complementary logic control versus DG411 - logic low enables conduction (ON), logic high disables (OFF). Each switch features symmetrical on-resistance across the full analog range and operates with rail-to-rail analog voltage handling up to ±15 V when powered by ±15 V supplies.
It uses Vishay Siliconix's high-voltage silicon gate process with epitaxial layer latchup protection, enabling 44 V maximum supply rating and guaranteed channel isolation of 68 dB (OIRR) at 1 MHz. Switching performance remains stable over –55 °C to +125 °C without derating below 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full-rail bipolar signal switching without clipping in precision instrumentation. |
| rDS(on) Typ. | 25 Ω - ensures minimal gain error and THD degradation in 12-bit+ data acquisition paths. |
| tON / tOFF | 110 ns / 100 ns - enables multiplexing rates >5 MHz in high-speed sampling systems. |
| Charge Injection | 5 pC - limits settling error to <1 LSB in 16-bit ADC front-ends with ≤10 nF hold capacitors. |
| OIRR | 68 dB - suppresses crosstalk between adjacent channels in multi-channel sensor interfaces. |
| Supply Range | ±15 V or +5 V to +44 V - allows direct integration into both bipolar op-amp circuits and unipolar industrial PLC I/O modules. |
| Logic Compatibility | TTL/CMOS - interfaces directly with microcontrollers and FPGAs without level-shifting circuitry. |
Pinout & Package
Package: 16-pin Ceramic Dual-In-Line Package (CerDIP), hermetically sealed, rated for –55 °C to +125 °C operation, with 0.3-inch body width and 0.1-inch lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control inputs | Active-low enables: logic 0 = switch ON; logic 1 = switch OFF (complementary to DG411). |
| S1–S4 | Switch source terminals | Bidirectional analog input/output nodes; each connects to corresponding Dx when switch is ON. |
| D1–D4 | Switch drain terminals | Bidirectional analog output/input nodes; conduct equally well in either direction when enabled. |
| V+ | Positive analog supply | Accepts up to +44 V; sets upper analog rail; must be ≥ |V–| for symmetric operation. |
| V– | Negative analog supply | Accepts down to –44 V; sets lower analog rail; required for bipolar signal handling. |
| GND | Analog ground reference | Return path for analog signals; separate from digital logic ground (VL) to minimize noise coupling. |
| VL | Logic supply voltage | Supplies internal level shifters; typically +5 V; accepts (GND –0.3 V) to (V+) +0.3 V. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Prevents momentary shorting between channels during state transitions - critical for fault-tolerant multiplexer designs. |
| Ultra-low charge injection (5 pC) | Minimizes voltage glitches on sampling capacitors, enabling accurate DC-coupled measurements in precision ADC drivers. |
| On-resistance flatness & matching | ≤10 Ω variation across ±15 V signal range - preserves linearity and channel-to-channel gain consistency. |
| Latchup immunity | Epitaxial substrate prevents destructive latchup even under overvoltage or ESD stress conditions. |
| Wide supply flexibility | Operates from ±5 V to ±15 V dual supplies or +5 V to +44 V single supply - simplifies power architecture in mixed-signal systems. |

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 |
|---|---|---|---|
| ADG412BRZ | 28 Ω rDS(on), 125 ns tON, –40 °C to +85 °C, 16-pin SOIC | Lower temp grade and plastic package - suitable for commercial-grade portable equipment only. | Select ADG412BRZ when cost and board space are prioritized over extended temperature and hermetic reliability. |
| MAX4612CPI+ | 35 Ω rDS(on), 130 ns tON, –40 °C to +85 °C, 16-pin PDIP | Higher on-resistance and wider temp range gap - requires recalibration in precision ATE environments. | Choose MAX4612CPI+ only for legacy designs where pin compatibility with older Maxim layouts is mandatory. |
Compared with DG412AK-E3, ADG412BRZ offers lower cost but sacrifices military-grade temperature range and hermetic sealing, while MAX4612CPI+ trades on-resistance performance for broader vendor support - making DG412AK-E3 the optimal choice for high-reliability, wide-temperature, precision analog routing.

FAQ
What is the operating temperature range of the DG412AK-E3?
The DG412AK-E3 is rated for operation from –55 °C to +125 °C, validated per MIL-PRF-19500/530 and qualified to Class B for high-reliability applications. This range is enabled by its ceramic DIP package and Vishay Siliconix's high-voltage silicon gate process, making DG412AK-E3 suitable for aerospace, defense, and downhole industrial systems where thermal stability is critical.
Does the DG412AK-E3 support single-supply operation?
Yes, the DG412AK-E3 supports single-supply operation from +5 V to +44 V. In this configuration, V+ is connected to VL and V– is tied to ground. The device maintains specified performance including 25 Ω rDS(on) and 110 ns tON at +12 V, and its input switching thresholds scale with VL - ensuring reliable logic interfacing across the full supply range. DG412AK-E3 does not require external level shifters in unipolar systems.
How does the DG412AK-E3 differ from the DG411AK-E3 in control logic?
The DG412AK-E3 uses inverted control logic relative to the DG411AK-E3: a logic low (≤0.8 V) on INx turns the corresponding switch ON, while a logic high (≥2.4 V) turns it OFF. In contrast, DG411AK-E3 activates switches with logic high. This complementary behavior allows designers to select either part based on system-level control architecture - DG412AK-E3 eliminates need for external inverters when driving from open-drain or active-low controllers.
What is the maximum analog signal voltage the DG412AK-E3 can handle?
The DG412AK-E3 supports analog signals from V– to V+, with a maximum differential supply rating of 44 V. When operated at ±15 V supplies, it handles analog voltages from –15 V to +15 V continuously. Signals exceeding V+ or V– are clamped by internal diodes, but forward current must be limited to 30 mA continuous or 100 mA pulsed (1 ms, 10% duty cycle) to avoid damage. DG412AK-E3 maintains specified rDS(on) and leakage performance across this full range.
Is the DG412AK-E3 pin-compatible with other devices in the DG411/412/413 family?
Yes, all members of the DG411/412/413 family share identical 16-pin CerDIP, DIP, SOIC, and LCC pinouts - including DG412AK-E3. Pin functions (IN1–IN4, S1–S4, D1–D4, V+, V–, GND, VL) are electrically and physically identical across variants. This allows drop-in replacement between DG411AK-E3, DG412AK-E3, and DG413AK-E3 in existing PCB layouts, with only logic polarity or switch configuration (NO/NC) differing per part number.
