    • 1 The 1-wire 48 × 1 and the 2-wire 24 × 1 multiplexer topologies can enable a unity gain amplifier to reduce FET settling time.
    • 2 Path resistance is a combination of relay contact resistance and trace resistance. Contact resistance typically remains low for the life of a relay. At the end of relay life, the contact resistance rapidly rises above 1.0 Ω.
    • 3 Certain applications might require additional time for proper settling. For information about including additional settling time, refer to the NI Switches Help.
