Notes:
a. Application hints are for DESIGN AID ONLY, not guaranteed and not subject to production testing.
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 RDS(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.)
