DESCRIPTION
The DG1408 is a precision analog multiplexer comprising eight single-ended channels. The DG1409 is a dual four single-ended channels analog multiplexer. Built on a new CMOS process, the Vishay Siliconix DG1408 and DG1409 offer low on-resistance of 3.2 Ω. The low and flat resistance over the full signal range provides excellent linearity and low signal distortion. The new CMOS platform also ensures ultra low power dissipation, minimized parasitic capacitance, and low charge injection.
