DG412LAK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG412LAK is a quad single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It features a ceramic dual in-line package (CDIP) with 16 pins. The device operates on a single supply voltage ranging from 2.7V to 12V or dual supplies of ±3V to ±6V. Key electrical specifications include a maximum on-resistance of 17 ohms, a -3dB bandwidth of 280MHz, and charge injection of 5pC. Switching times are specified at a maximum of 19ns for turn-on and 12ns for turn-off. The component supports an operating temperature range from -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• High-speed switching capability with 280MHz bandwidth
• Low charge injection of 5pC for signal integrity
• Robust ceramic packaging for extended temperature operation

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG412LAK belongs to the DG41x series of CMOS analog switches. Unlike standard plastic packages, this specific variant utilizes a ceramic DIP construction, which typically offers superior thermal stability and hermetic sealing compared to epoxy-based packages. It is part of a family that includes variants like the DG411 and DG413, differentiated primarily by contact type and resistance values.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public records indicate the DG412LAK is obsolete. Potential replacements within the same family include the DG411LAK or DG413LAK, though these differ in contact configuration (normally closed vs normally open) and on-resistance characteristics. Verification against current active datasheets is required before substitution.
