GENERAL DESCRIPTION

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 and is compatible with standard SPI, QSPI?, MICROWIRE?, and DSP interface standards. The output of the shift register, SDO, enables a number of the ADG1438/ADG1439 parts to be daisy-chained. On power-up, the internal shift register contains all zeros, and all switches are in the off state.
