Electronic DPDT Switch

Switch It should be appreciated that the output impedance of the switch is fairly high and so for low signal distortion, a load greater than 10kS2 is necessary.
Using a high supply voltage (1 0-1 5V) also helps to achieve this end. The gates will pass signals above the 10MHz mark but as the frequency becomes higher, crosstalk between the switchesand distortion will inevitably increase.
