The DG381A/384A/387A/390A are monolithic CMOS analog switches designed for applications in instrumentation, communications, and process control. These switches are ideal for battery powered applications, without sacrificing switching speed.
The DG381A/384A/387A/390A series of monolithic CMOS analog switches is designed for instrumentation, communications, and process‑control applications that require fast switching and low on‑resistance across the full supply range. The devices operate from a single positive supply or from dual ±15 V rails and are suitable for battery‑powered designs.
The datasheet includes detailed pin‑out diagrams, absolute maximum ratings, electrical specifications such as supply voltage range, continuous current, and operating temperature, as well as typical characteristic curves for turn‑on/off times, break‑before‑make behavior, and leakage currents.
| Supply Voltage Range | ±15 V |
|---|---|
| Operating Temperature Range | −25 °C to 125 °C (varies by package) |
The analog signal range is full –15 V to +15 V.
Typical turn‑on time is about 150 ns at 25 °C.
Yes, single‑supply operation is allowed by connecting the V‑ rail to 0 V.
