DG411LAK

DG411LAK Description

The DG411LAK is a high-performance, single-pole single-throw (SPST) analog switch designed for a wide range of applications requiring precise signal routing and control. Manufactured by Vishay / Siliconix, this obsolete product is part of the DG411 family and is housed in a through-hole 16-CERDIP package. The DG411LAK features a maximum on-state resistance of 17 ohms and operates within a wide supply voltage range of ±3V to ±6V for dual supplies and 2.7V to 12V for single supplies. It offers a -3dB bandwidth of 280MHz, making it suitable for high-frequency applications. The switch exhibits low leakage current (250pA max) and low charge injection (5pC), ensuring minimal signal distortion. With a channel capacitance of 5pF and 6pF for CS(off) and CD(off) respectively, and a fast switch time of 19ns for turn-on and 12ns for turn-off, the DG411LAK delivers reliable performance in signal switching applications.
