DG381ACWE

Analog Switches, Multiplexers, Demultiplexers Overview

The DG381ACWE is a dual single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates with a maximum on-resistance of 50 Ohms and supports dual supply voltages ranging from ±5V to ±18V, or a single supply from 10V to 30V. The device features a maximum turn-on time of 300 ns and a turn-off time of 250 ns. It is housed in a 16-SOIC package and functions within an operating temperature range of 0°C to +70°C. The component draws a maximum supply current of 500 uA and handles a DC switch current of 30 mA.
