Vishay – DG1408: 8-Channel Precision Multiplexer with Low 3.2Ω On-Resistance and 17μA Power Consumption

Vishay_October2014_pg12Vishay-logo
The 8-channel precision analog multiplexer is built on a new CMOS process; the DG1408 combines low on-resistance of 3.2Ω with extremely low power dissipation, parasitic capacitance, and charge injection.

Compared to previous generation and competing analog switches with similar on-resistance in the same footprint, the DG1408 offers 25% lower on-resistance, 10% lower drain parasitic capacitance, and up to 30% lower charge injection. In addition, the
device´s new CMOS platform ensures low and flat resistance over the full signal range, providing excellent linearity and low signal distortion.
