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:

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.)
