DG301AAZ/883

Analog Switches, Multiplexers, Demultiplexers Overview

The DG301AAZ/883 is a high-reliability single-pole double-throw (SPDT) analog switch manufactured by Vishay Siliconix. Designed for military and aerospace applications, it utilizes hermetic ceramic packaging to ensure stability in extreme environments. The device features a single channel with a maximum on-resistance of 50 ohms and supports dual supply voltages up to ±15 V. It operates within a temperature range of -55°C to +125°C, offering a maximum switching time of 300 ns and an off-time of 250 ns. This component is suitable for precision signal routing where environmental ruggedness and low power consumption are critical requirements.
