APPLICATIONS
The DG300B series of analog switches will switch positive
analog signals while using a single positive supply. This
facilitates their use in applications where only one supply is
available. The trade-offs of using single supplies are:
1) Increased r_DS(on); 2) slower switching speed. The analog
voltage should not go above or below the supply voltages
which in single operation are V+ and 0 V. (See Input Switching
Threshold vs. Positive Supply Voltage Curve.)
