DG304AAA

Analog Switches, Multiplexers, Demultiplexers Overview

The DG304AAA is a dual single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 10 V to 30 V for single supplies, or ±5 V to ±18 V for dual supplies. The device features a maximum on-resistance of 50 Ohms and supports a DC switch current of 30 mA. Switching times are specified with a maximum turn-on time of 300 ns and a maximum turn-off time of 250 ns. It is housed in a TO-100-10 package designed for through-hole mounting and functions reliably across an extended temperature range from -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm that the specific ordering suffix matches the required package and temperature grade. Request original datasheets and material declarations to ensure compliance with project specifications before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual isolated analog switching is required within a wide voltage window. Ensure the application load does not exceed the 30 mA DC switch current limit. Verify that the TO-100-10 through-hole footprint aligns with the PCB layout requirements. Consider thermal dissipation capabilities given the 533 mW power dissipation rating at elevated temperatures.
