DG301B CMOS Analog Switches

* oLow level switching circuits

* oProgrammable gain amplifiers

* oPortable and battery powered systems

* oThe 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:

* oIncreased RDS(on)

* oSlower 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”)
