Multiplexer for AD7746

Question

Hi, I would set up two AD7746 converters in the same circuit, but I need to use a MUX in order to select the different bus from the two converters getting the readings from these simultaneously. I wonder if there was any particular I2C compatible MUX from Analog Devices, or however one that would fit for this purpose. Thanks

Hi, 
 The ADG728 is an I2C compatible Low voltage, 8:1 Mux. 
 
 However if you just have two ADCs you might only need a 2:1 configuration such as the ADG779 . With a 2:1 configuration it can be more efficient to use parallel control.
