Applications The DG300A series of analog switches will switch positive 1) Increased rpsjony; 2) slower switching speed. The analog analog signals while using a single positive supply. This voltage should not go above or below the supply voltages facilitates their use in applications where only one supply is which in single operation are V+ and 0 V. (See Input available. The trade-offs of using single supplies are: Switching Threshold vs. Positive Supply Voltage Curve.) P-32167Rev.
