The ADG739 is a CMOS analog matrix switch with a serially-controlled 3-wire interface. The ADG739 is a dual 4-channel matrix switch. On resistance is closely matched between switches and very flat over the full signal range.
The ADG739 utilize a 3-wire serial interface that is compatible with SPI™, QSPI™, MICROWIRE®, and some DSP interface standards. The output of the input shift register, DOUT, enables a number of these parts to be daisy-chained. On power-up, the internal input shift register contains all zeros and all switches are in the off state.
