ADG1439BRUZ-REEL7中文资料亚德诺数据手册PDF规格书

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.
