ADG791G中文资料亚德诺数据手册PDF规格书

GENERAL DESCRIPTION

The ADG791A/ADG791G are monolithic CMOS devices comprising four 2:1 multiplexers/demultiplexers controllable via a standard I2C serial interface. The CMOS process provides ultralow power dissipation yet gives high switching speed and low on resistance.

The on-resistance profile is very flat over the full analog input range and wide bandwidth ensures excellent linearity and low distortion. These features, combined with a wide input signal range make the ADG791A/ADG791G the ideal switching solution for a wide range of TV applications including S-video, RGB, and YPbPr video switches.
