DG301AAK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG301AAK is a monolithic CMOS analog switch from the DG301A_MIL series, manufactured by Vishay Siliconix. It features a single SPDT configuration housed in a 10-pin metal can package (TO-100-10). The device operates with dual supplies of ±15 V and supports full rail-to-rail analog signal ranges. Key electrical parameters include a maximum on-resistance of 50 Ω, a turn-on time of 300 ns, and a turn-off time of 250 ns. It offers low power dissipation of 450 mW and functions within an operating temperature range of -55 °C to +125 °C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• SPDT Configuration: Provides one single-pole double-throw switching path for precise signal routing.
• High Voltage Blocking: Designed to block up to 30 V peak-to-peak when off, ensuring robust isolation.
• Latch-up Proof Construction: Utilizes an epitaxial layer to prevent latch-up under high voltage stress conditions.
• Break-Before-Make Action: Ensures sequential switching to prevent short circuits between output terminals.

Analog Switches, Multiplexers, Demultiplexers Applications

• Low level switching circuits requiring minimal signal distortion
• Programmable gain amplifiers with digital control
• Portable and battery powered systems due to low power consumption

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required military-grade specifications. Check current lifecycle status as non-hermetic variants may be obsolete. Ensure proper handling procedures are followed for the metal can package during assembly.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring a single SPDT switch with high voltage blocking capabilities. Consider the 10-pin metal can package for hermetic sealing requirements. Evaluate the 50 Ω on-resistance against signal integrity needs. Verify compatibility with CMOS logic levels for control inputs.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the break-before-make time for the DG301AAK?

The break-before-make time is typically 50 ns at room temperature.

Can the DG301AAK operate with a single supply?

Yes, single supply operation is allowed by connecting the V- rail to 0 V, though this may increase on-resistance and reduce switching speed.

What is the maximum continuous current rating for the switches?

The continuous current rating for any terminal is 30 mA, while the source/drain current can handle up to 100 mA pulsed.
