DG300AAK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG300AAK is a monolithic CMOS analog switch manufactured by Vishay Siliconix, housed in a 14-pin CerDIP package. It features two independent single-pole single-throw (SPST) channels with full rail-to-rail analog signal range capability from -15 V to +15 V. The device operates on dual supplies of ±15 V or a single supply up to 30 V. Key electrical parameters include a maximum drain-source on-resistance of 50 Ω, a turn-on time of 300 ns, and a turn-off time of 250 ns. Power dissipation is rated at 825 mW, with a continuous current capacity of 100 mA per channel.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm the specific ordering suffix matches the required military or commercial grade specifications. Check for obsolescence status as non-hermetic versions are obsolete; consult the datasheet for pin-for-pin replacement options if necessary.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring precision analog switching with low leakage and high isolation. Ensure the design accommodates the specified power dissipation limits and thermal derating requirements above 75°C. Verify that the logic input levels align with the system's control voltage standards for reliable ON/OFF state determination.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG300A_MIL series of CMOS analog switches, which also includes SPDT and DPST configurations. The series is designed for communications, instrumentation, and process control applications where low leakage and low power are critical. It utilizes the PLUS-40 CMOS process for enhanced reliability.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Non-hermetic versions are obsolete. Use the DG300B Series as pin-for-pin replacements. For hermetic requirements, consider the DG300AAK/883 variant or other JM38510 qualified parts listed in the ordering information.
