APPLICATIONS
The DG300A_MIL 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.)
