ADG1438 - iCMOS Multiplexers/Matrix Switches
The ADG1438 and ADG1439 are CMOS analog matrix switches with a serially controlled 3-wire interface.
The ADG1438 is an 8-channel matrix switch, and the ADG1439 is a dual 4-channel matrix switch.
The ADG1438/ADG1439 use a versatile 3-wire serial interface that operates at clock rates of up to 50 MHz
