AN301 Datasheet High-speed Dmos Fet Analog Switches And Switch Arrays

Manufacturer: TEMIC Semiconductors (now Microchip)

Overview: AN301 High-Speed DMOS FET Analog Switches and Switch Arrays Jack Armijos Introduction This Application Note describes in detail the principle of operation of the SD210/5000 series of high-speed analog switches and switch arrays. It contains an explanation of the most important switch characteristics, application examples, test data, and other application hints.

General Description

The Siliconix SD210 and SD5000 series are discretes and quad monolithic arrays, respectively, of single-pole single-throw analog switches.

These switches are n-channel enhancement-mode silicon field effect transistors built using double-diffusion MOS (DMOS) silicon gate technology.

Surface-mount versions (SST211, SD5400 Series) are also available.

Key Features

  • the amplitude of the gate-voltage excursion. This is a directly proportional relationship: the larger the Switching spikes occur at switch turn-on as well as turn-off time. W.
