DVD-R/RW AV receivers GENERAL DESCRIPTION The ADG795A/ADG795G are monolithic CMOS devices that allow up to eight devices on the same bus. This allows the comprising five 2:1 multiplexers/demultiplexers controllable via user to expand the capability of the device by increasing the size 2 a standard I C serial interface. The CMOS process provides of the switching array. ultralow power dissipation, yet gives high switching speed and The ADG795A/ADG795G operate from a single 3 V or 5 V low on resistance. supply voltage and are available in a compact 4 mm 4 mm The on-resistance profile is very flat over the full analog input body, 24-lead, lead-free package (LFCSP). range and wide bandwidth ensures excellent linearity and low PRODUCT HIGHLIGHTS distortion. These features, combined with a wide input signal range make the ADG795A/ADG795G the ideal switching 1. Wide bandwidth: 325 MHz. solution for a wide range of TV applications including S-video, 2.
