Product details
Overview
DG301AAK/883B from Maxim Integrated is a dual SPDT (single-pole double-throw) CMOS analog switch designed for precision signal routing in high-reliability systems. It features <50Ω on-resistance, ±15V analog signal range (V+ to V−), break-before-make switching, 150ns turn-on time, and operates across −55°C to +125°C. It is used in military-grade telemetry interfaces requiring low charge injection (<12pC) and latchup-proof operation.
For engineers reviewing the DG301AAK/883B datasheet, DG301AAK/883B pinout, DG301AAK/883B application, or DG301AAK/883B equivalent, key selection criteria include its 10-lead metal-can hermetic package, MIL-PRF-38535 Class B qualification (883B), dual SPDT topology with independent TTL/CMOS-compatible controls, and guaranteed performance over extended temperature and dual-supply (±5V to ±18V) conditions.
Technical Context
The DG301AAK/883B implements two independent SPDT switches using monolithic CMOS process technology with substrate isolation. Each switch channel supports rail-to-rail analog signals from V− to V+, with matched on-resistance (typ. 40Ω at ±15V) and <10% inter-channel RDS(ON) matching. Its break-before-make timing (50ns minimum) prevents signal shorting during state transitions.
Control logic accepts TTL- and CMOS-level inputs (0.8V/4.0V thresholds), enabling direct interface with microcontrollers and FPGAs without level-shifting. The device draws only 0.5mA positive supply current and sub-1µA negative supply current under static conditions, supporting low-power portable and battery-backed instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - Supports full-rail switching from V− to V+ with no signal clipping. |
| On-Resistance | <50Ω - Ensures minimal voltage drop and signal attenuation in precision gain-setting paths. |
| Turn-On Time | 150ns - Enables fast multiplexing in data acquisition systems sampling up to ~3MHz. |
| Charge Injection | 12pC - Limits settling error in sample-and-hold circuits to <1LSB for 12-bit 10kΩ input impedance. |
| Off-Leakage Current | <0.1nA - Maintains accuracy in high-impedance sensor front-ends and integrator applications. |
| Supply Range | ±5V to ±18V - Allows flexible biasing in mixed-signal systems with legacy ±15V rails. |
| Operating Temp | −55°C to +125°C - Qualified per MIL-PRF-38535 Class B for aerospace and defense platforms. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 6 | IN1 | Control input for Switch 1; TTL/CMOS compatible (0.8V/4.0V thresholds). |
| 7 | IN2 | Control input for Switch 2; independent of IN1, enables asynchronous routing. |
| 8 | S2 | Common terminal of Switch 2; connects to D3 or D4 based on IN2 logic state. |
| 9 | D3 | Throw 1 of Switch 2; selected when IN2 = HIGH. |
| 10 | D4 | Throw 2 of Switch 2; selected when IN2 = LOW. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guarantees 50ns minimum dead time between throw disconnection and reconnection, preventing momentary shorts in power-switching or relay-replacement circuits. |
| Latchup-proof CMOS construction | Immune to destructive latchup under transient overvoltage or ESD events, critical for unattended field-deployed systems. |
| Single-supply capability | Operates with V− tied to GND and V+ = +10V to +30V, simplifying power architecture in industrial PLC I/O modules. |
| Low charge injection (12pC) | Minimizes voltage glitch on hold capacitors, enabling accurate DC-coupled sample-and-hold in precision ADC front-ends. |
| Rail-to-rail analog range | Switches signals from V− to V+ without distortion, supporting bipolar sensor outputs (e.g., ±10V accelerometers) directly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRZ | 8-channel single-pole analog multiplexer; 75Ω RDS(ON); −40°C to +85°C; SOIC-16 package. | Higher channel count but lower temperature rating and no MIL-spec qualification. | Select ADG408BRZ only for commercial-grade, space-constrained PCBs where extended temperature and hermetic sealing are unnecessary. |
| HI-506ACD | Quad SPST switch; 60Ω RDS(ON); −55°C to +125°C; CERDIP-16; requires external logic for SPDT emulation. | Requires two channels + external inverters to emulate one SPDT function; higher board area and component count. | Choose HI-506ACD only if existing design uses quad SPST topology and cannot accommodate dual SPDT pinout. |
Compared with DG301AAK/883B, ADG408BRZ offers greater channel density but lacks military temperature range and hermetic packaging, while HI-506ACD matches the temperature spec but increases design complexity and footprint to achieve equivalent SPDT functionality.
