Product details
Overview
DG301AAK from Vishay Siliconix is a hermetically sealed, military-grade SPDT analog switch in a 10-pin metal can package, featuring ±15 V analog signal range, 30 Ω typical on-resistance, 150 ns turn-on time, and break-before-make switching-designed for precision signal routing in high-reliability instrumentation and aerospace telemetry systems.
For engineers reviewing the DG301AAK datasheet, DG301AAK pinout, DG301AAK application, or DG301AAK equivalent, this page delivers verified electrical parameters, validated pin functions, MIL-STD-883-compliant operating conditions, and direct alternatives with documented functional alignment and known trade-offs in rail-to-rail conduction and leakage performance.
Technical Context
The DG301AAK implements a dual-channel, single-pole double-throw (SPDT) CMOS analog switch architecture with independent digital control inputs (IN1, IN2) enabling complementary switching of two separate analog paths (S1/D1 and S2/D2). Its substrate-connected V+ pin provides hermetic case biasing critical for latch-up immunity in harsh environments.
Designed on the Vishay PLUS-40 CMOS process, it supports true bidirectional conduction with zero offset voltage, operates over –55 °C to +125 °C, and blocks up to ±30 V peak-to-peak when off-enabling robust signal integrity in wide-dynamic-range measurement front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full rail-to-rail analog signals without clipping across industrial/military supply rails |
| Drain-Source On-Resistance | 30 Ω typ - ensures minimal signal attenuation and gain error in precision amplifier gain-switching networks |
| Turn-On Time | 150 ns - enables sub-microsecond channel selection in real-time data acquisition systems |
| Break-Before-Make Time | 50 ns - prevents momentary short-circuit between analog sources during switching transitions |
| Off-Leakage Current | ±100 nA max at hot temp - preserves DC accuracy in high-impedance sensor interfaces and integrator circuits |
| Supply Current | 0.5 mA max - sustains low power draw in battery-backed or thermally constrained avionics modules |
| Charge Injection | 8 pC - limits voltage glitch amplitude in sample-and-hold stages using small hold capacitors |
Pinout & Package
Package: 10-pin metal can (hermetic), with V+ connected to substrate and case for EMI shielding and thermal grounding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | S2 | Switch terminal 2 - connects to second analog source path in SPDT configuration |
| 2 | V− | Negative supply rail - referenced to analog ground; sets lower bound of signal swing |
| 3 | D2 | Drain 2 - output node for second switched analog path |
| 4 | D1 | Drain 1 - output node for first switched analog path |
| 5 | V+ (Substrate and Case) | Positive supply and mechanical ground - ties case to V+ for latch-up suppression and shielding |
| 6 | S1 | Switch terminal 1 - connects to first analog source path in SPDT configuration |
| 7 | IN1 | Digital control input 1 - activates S1/D1 path when logic high (≥4 V) |
| 8 | GND | Digital ground reference - separates logic return from analog ground to minimize noise coupling |
| 9 | IN2 | Digital control input 2 - activates S2/D2 path when logic high (≥4 V); complementary to IN1 |
| 10 | NC | No connect - internally unconnected; must remain floating per MIL-STD-883 requirements |
Key Features
| Feature | Design Value |
|---|---|
| Latch-up proof construction | Epitaxial layer prevents parasitic SCR activation - essential for operation in radiation-prone or high-transient environments |
| True bidirectional conduction | No offset voltage in on-state - preserves signal polarity and DC accuracy in both directions for differential sensor routing |
| Hermetic metal-can packaging | Meets MIL-STD-883 requirements for humidity resistance and long-term reliability - qualified for space-qualified and flight-critical hardware |
| CMOS and quasi-TTL compatible inputs | Logic thresholds at 0.8 V (low) and 4 V (high) - interoperable with legacy 5 V logic families without level-shifting |
| Single-supply operation capability | V− tied to 0 V enables use in +15 V only systems - simplifies power architecture in portable test equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG301AAK/883B | Same die, updated process revision (PLUS-40B); identical pinout and specs, improved leakage uniformity at hot temp | Qualified to same MIL-STD-883 test flow but with tighter IS(off) distribution - preferred for new designs requiring statistical process control | Select DG301AAK/883B if sourcing new production lots; DG301AAK remains valid for legacy repair and obsolescence mitigation |
| ADG5412BRUZ | 4-channel SPDT, 12-bit DAC-compatible, 10 Ω rDS(on), but requires external V− and lacks hermetic packaging | Not MIL-qualified; suitable for commercial industrial PLCs but not flight hardware due to non-hermetic LFCSP package and no 883 screening | Use ADG5412BRUZ only in cost-sensitive, non-mission-critical applications where ±15 V rail-to-rail operation and 100 nA leakage are sufficient |
Compared with DG301AAK, DG301AAK/883B offers enhanced parametric consistency for high-volume qualification testing, while ADG5412BRUZ trades hermetic reliability and MIL screening for lower on-resistance and integrated channel count-making it viable only in non-aerospace, non-military contexts.

FAQ
What is the maximum analog signal voltage range supported by DG301AAK?
The DG301AAK supports a full rail-to-rail analog signal range of ±15 V when operated with V+ = +15 V and V− = −15 V. This is guaranteed by design and enables accurate switching of bipolar signals without clipping in precision measurement systems. The device blocks up to ±30 V peak-to-peak when off, ensuring robust protection against overvoltage transients in harsh environments.
Does DG301AAK require dual supplies, or can it operate from a single supply?
Yes, DG301AAK supports single-supply operation: tie V− to 0 V and apply V+ = +15 V. In this mode, the analog signal range becomes 0 V to +15 V. Note that rDS(on) increases and switching speed decreases slightly versus dual-supply operation-but the DG301AAK remains fully functional and retains its break-before-make timing and latch-up immunity.
What does the "/883" suffix indicate in DG301AAK/883?
The "/883" suffix denotes compliance with MIL-STD-883, including full screening for vibration, thermal shock, burn-in, and parameter verification across −55 °C to +125 °C. DG301AAK/883 is tested to Method 5005 for hermeticity and Method 2015 for life testing-making it suitable for flight-critical and high-reliability defense applications where standard commercial parts are unacceptable.
Is DG301AAK pin-compatible with other DG300A_MIL family members?
No-DG301AAK (10-pin metal can) is not pin-compatible with DG300AAK or DG302AAK (both 14-pin CerDIP). Pin counts, layouts, and internal configurations differ: DG301AAK is SPDT with two independent control inputs, while DG300AAK is SPST and DG302AAK is DPST. Always verify pinout diagrams and truth tables before substitution.
What is the purpose of connecting V+ to the substrate and case in DG301AAK?
Connecting V+ to the substrate and metal can in DG301AAK establishes a fixed potential across the silicon die's backside, preventing latch-up by eliminating parasitic PNPN paths. It also provides EMI shielding and thermal conduction-critical for maintaining signal integrity and reliability in high-noise aerospace and radar environments where the DG301AAK is commonly deployed.
