Product details
Overview
DG301AAK/883 from Vishay Siliconix is a military-grade, hermetically sealed SPDT CMOS analog switch in a 14-pin ceramic DIP package, rated for -55 °C to +125 °C operation. It features ±15 V analog signal range, 30 Ω typical on-resistance, 150 ns turn-on time, break-before-make switching, and rail-to-rail analog conduction-used in precision instrumentation amplifier gain/input selection circuits requiring latch-up immunity and low leakage.
For engineers reviewing the DG301AAK/883 datasheet, DG301AAK/883 pinout, DG301AAK/883 application, or DG301AAK/883 equivalent, key selection criteria include guaranteed break-before-make timing (50 ns), dual-supply ±15 V operation with GND reference, 100 nA max hot off-leakage, and MIL-PRF-38535 Class B qualification per ordering suffix /883.
Technical Context
The DG301AAK/883 implements a monolithic SPDT switch using Vishay's PLUS-40 CMOS process with epitaxial isolation to prevent latch-up. Its control logic accepts TTL- and CMOS-compatible inputs (0.8 V low, 4 V high) and drives two complementary switches with precise timing coordination.
Designed for break-before-make operation, it guarantees 50 ns minimum open interval between S1/D1 and S2/D2 paths. Analog conduction is bidirectional with no offset voltage, and the substrate is tied to V+ (case-connected), requiring careful PCB grounding to avoid noise coupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full rail-to-rail signal switching without clipping when V+ = +15 V and V− = −15 V |
| Drain-Source On-Resistance | 30 Ω typ - ensures minimal signal attenuation and gain error in precision analog paths |
| Turn-On Time | 150 ns - enables fast channel selection in data acquisition and multiplexed sensor systems |
| Break-Before-Make Time | 50 ns - prevents momentary shorting between analog sources during switching transitions |
| Off-Leakage Current | 100 nA max at +125 °C - maintains signal integrity in high-impedance measurement circuits |
| Charge Injection | 8 pC - limits voltage glitch on sampled-hold nodes and integrator inputs |
| Supply Current | 0.5 mA max - supports low-power operation in battery-backed or thermally constrained systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Single-supply only (up to +36 V); no negative rail support; 4.5 Ω rDS(on); 12-lead TSSOP | Not suitable for bipolar ±15 V signal routing; limited to unipolar industrial I/O modules | Select only if system uses single positive supply and requires lower on-resistance |
| MAX4677ESE+ | ±15 V capable; 45 Ω rDS(on); 16-lead SOIC; commercial temp range only (−40°C to +85°C) | Lacks MIL-PRF-38535 qualification and extended temperature screening | Acceptable for non-military industrial designs where cost and footprint are prioritized over reliability certification |
Compared with ADG1419BRUZ and MAX4677ESE+, the DG301AAK/883 uniquely delivers MIL-qualified hermetic packaging, guaranteed break-before-make timing, and true bipolar ±15 V analog switching-making it irreplaceable in flight-critical and space-qualified signal routing where parameter stability across extreme temperature and radiation exposure is mandatory.

FAQ
What is the maximum analog signal voltage range supported by the DG301AAK/883?
The DG301AAK/883 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 switching of bipolar signals without clipping or distortion in precision instrumentation applications.
Does the DG301AAK/883 require external pull-up or pull-down resistors on its digital control inputs?
No, the DG301AAK/883 does not require external biasing resistors on IN1 or IN2. Its TTL/CMOS-compatible inputs have defined thresholds (0.8 V max for logic low, 4 V min for logic high) and draw less than 1 µA input current, allowing direct connection to FPGA or microcontroller GPIO pins.
How is the substrate connection handled in the DG301AAK/883 package?
In the DG301AAK/883, the substrate and metal case are internally bonded to the V+ pin (Pin 12). This requires the PCB mounting pad for Pin 12 to serve as both the positive supply connection and the mechanical ground plane anchor, with attention to thermal and EMI isolation from sensitive analog traces.
Can the DG301AAK/883 operate from a single +15 V supply?
Yes, the DG301AAK/883 can operate from a single +15 V supply by connecting V− (Pin 1) to GND. However, this reduces the analog signal range to 0 V to +15 V and increases rDS(on) and switching time versus dual-supply operation-trade-offs documented in the Application Hints section of the datasheet.
What is the purpose of the break-before-make timing specification for the DG301AAK/883?
The break-before-make timing (50 ns minimum) ensures that the DG301AAK/883 fully disconnects one analog path before connecting the other. This prevents momentary short-circuits between independent signal sources-critical in applications like programmable gain amplifiers where unintended inter-channel coupling would cause gain errors or system instability.
