• Manufacturer Part Number: AN201
• Description: High-performance Multiplexing With The DG408
• Manufacturer: Vishay Intertechnology

Conclusion
For
high-performance systems, their design must incorporate the
latest technological advances. As digital controllers are
becoming faster and analog sources more accurate, the
modern multiplexer must reflect these advances to become a
stronger link in the transition from the analog to the digital
world. The DG408 and DG409 are designed to meet these
new
Vishay Siliconix’ commitment to serve our customers’ needs
for state-of-the-art technology.
