DG305AAA

Analog Switches, Multiplexers, Demultiplexers Overview

The DG305AAA is a CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a single SPDT (Single Pole Double Throw) configuration housed in a CDIP-14 package designed for through-hole mounting. The device operates on dual power supplies ranging from ±5V to ±18V, with a maximum supply voltage of 30V. Key electrical parameters include a maximum on-resistance of 50 Ohms and a DC switch current of 30 mA. Switching performance is characterized by a maximum turn-on time of 250 ns and a maximum turn-off time of 150 ns. The component supports an operating temperature range from 0°C to +70°C and has a maximum power dissipation of 825 mW.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'AAA' against official manufacturer documentation to confirm pinout and electrical tolerances, as suffixes often denote package type or temperature grade. Confirm availability status, as this component may be discontinued or subject to last-time buy restrictions. Ensure the procurement channel provides valid traceability and authenticity guarantees for industrial-grade components.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG305AAA when a single-pole double-throw switching function is required within a dual-supply environment. Compare the 50 Ohm on-resistance and 250 ns switching speed against application timing requirements. Consider the CDIP-14 through-hole package constraints versus surface-mount alternatives like the DG305ACWE+ if PCB layout permits. Verify that the ±5V to ±18V supply range aligns with the system power architecture.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG305AAA belongs to the DG305A series of CMOS analog switches from Maxim Integrated, now part of Analog Devices. This series typically includes variants such as the DG304A (SPST), DG305A (SPDT), and DG306A (SPDT). These devices are engineered for applications requiring low distortion and fast switching, serving as fundamental building blocks in signal conditioning and multiplexing circuits.
