    Thread Summary
    
                The user inquired about a physical enable pin to turn off all switches on the ADG725, but the final answer clarified that the /EN function is represented by the MSB in the SPI data-bits, as shown in Figure 2 on Page 5 of the datasheet, and there is no dedicated physical enable pin.

    The truth table in the data sheet shows an Enable pin that turns off all switches.  Yet there doesn't seem to be such a pin on the device.  I would like to be able to turn off all switches.
