Product details
Overview
DG300AAK/883 from Vishay Siliconix is a hermetically sealed, military-grade SPST 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 latch-up-proof CMOS design for precision signal routing in harsh-environment instrumentation and aerospace systems.
For engineers reviewing the DG300AAK/883 datasheet, DG300AAK/883 pinout, DG300AAK/883 application, or DG300AAK/883 equivalent, this part supports rail-to-rail analog switching with break-before-make logic, single- or dual-supply operation, and low charge injection (8 pC) - critical for high-fidelity data acquisition and programmable gain amplifier front-ends.
Technical Context
The DG300AAK/883 implements a monolithic CMOS transmission gate architecture fabricated on Vishay's PLUS-40 process, with epitaxial isolation to prevent latch-up under ±30 V peak-to-peak off-state blocking. It operates across –55 °C to +125 °C and accepts TTL/CMOS-compatible digital inputs (0.8 V low / 4 V high).
Its dual-rail supply configuration (V+ and V−) enables true bipolar analog signal handling from –15 V to +15 V, while GND serves as logic reference and substrate connection is tied to V+ (case). The device is specified for ≤100 mA pulsed drain/source current and exhibits <100 nA off-leakage at hot temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full rail-to-rail AC/DC signal switching without clipping |
| rDS(on) Typ | 30 Ω - minimizes signal attenuation and gain error in precision amplifiers |
| tON Max | 300 ns - enables sub-microsecond channel selection in real-time control loops |
| Charge Injection | 8 pC - reduces settling error in sample-and-hold and multiplexed ADC circuits |
| Off-Leakage (Hot) | 100 nA - ensures low offset drift in high-impedance sensor interfaces |
| Supply Range | V+ = +15 V, V− = –15 V - allows symmetric bipolar operation or single-supply mode (V− = 0 V) |
| Operating Temp | –55 °C to +125 °C - qualified per MIL-PRF-38535 Class B for space and defense platforms |
Pinout & Package

| 4 | D2 | Drain terminal of Channel 2 - connects to load or downstream circuit |
| 5 | D1 | Drain terminal of Channel 1 - output node for switched analog signal |
| 6 | V+ (Case) | Positive supply rail and hermetic case connection - provides EMI shielding and thermal conduction |
| 7 | S1 | Source terminal of Channel 1 - primary analog input node |
| 8 | IN2 | Digital control input for Channel 2 - independent enable for dual SPST function |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG300BAAK/883 | PIN-compatible upgrade with improved rDS(on) matching (±5 % vs. ±25 %), lower tON (125 ns typ), and enhanced ESD rating (4 kV HBM). | Preferred for new designs requiring tighter channel matching and faster settling in high-speed DAQ. | Select DG300BAAK/883 when upgrading legacy DG300A-based systems where performance margin and long-term obsolescence risk are concerns. |
| HI-506AJ | 10-pin metal can, ±18 V analog range, higher rDS(on) (65 Ω typ), but superior hot-temperature leakage (<10 nA at 125 °C). | Better suited for ultra-low-leakage applications like electrometer-grade pH or ion sensors. | Choose HI-506AJ only when sub-10 nA off-leakage at max temperature outweighs on-resistance and speed requirements. |
Compared with DG300BAAK/883 and HI-506AJ, the DG300AAK/883 delivers optimal balance of speed, on-resistance, and hermetic reliability for MIL-SPEC instrumentation - though it lacks the tighter parametric tolerances of the B-series or the extreme low-leakage specialization of the HI-506AJ.

FAQ
What is the maximum analog signal voltage range supported by the DG300AAK/883?
The DG300AAK/883 supports a full rail-to-rail analog signal range of ±15 V when operated with V+ = +15 V and V− = –15 V. This range is guaranteed by design and enables undistorted switching of bipolar signals such as sensor outputs or audio waveforms in defense-grade instrumentation. Operation outside this range risks exceeding absolute maximum ratings and may cause permanent damage.
Does the DG300AAK/883 require dual supplies, or can it operate from a single supply?
The DG300AAK/883 supports both dual-supply (±15 V) and single-supply (V+ = +15 V, V− = 0 V) configurations. In single-supply mode, the analog input range is limited to 0 V to +15 V, and performance parameters such as rDS(on) and switching speed degrade slightly. The GND pin remains the logic reference regardless of supply configuration, and V+ is always tied to the metal case.
What does "V+ (Substrate and Case)" mean in the DG300AAK/883 pinout?
"V+ (Substrate and Case)" indicates that the metal can housing of the DG300AAK/883 is electrically connected to the V+ supply pin and forms part of the silicon substrate bias network. This design provides inherent EMI shielding, improves thermal dissipation, and ensures consistent substrate potential - critical for latch-up immunity and noise rejection in high-reliability systems. The case must be connected to V+ and not left floating.
Is the DG300AAK/883 pin-compatible with the DG300BAAK/883?
Yes, the DG300AAK/883 and DG300BAAK/883 share identical 10-pin metal can packaging, pinout, and footprint. The DG300BAAK/883 is explicitly documented as a pin-for-pin replacement offering improved specifications including lower rDS(on) variation, faster switching, and higher ESD tolerance - making it a direct drop-in upgrade for new designs or field replacements where enhanced performance is required.
What is the significance of the /883 suffix in DG300AAK/883?
The /883 suffix denotes compliance with MIL-PRF-38535 Appendix A, specifying Class B screening for high-reliability applications. This includes rigorous environmental testing (thermal shock, vibration, hermeticity), lot traceability, failure analysis protocols, and extended temperature qualification (–55 °C to +125 °C). The /883 variant is intended for aerospace, defense, and nuclear instrumentation where zero-defect operation and long-term reliability are non-negotiable.
