GENERAL DESCRIPTION The ADG793A/ADG793G are monolithic CMOS devices comprising three 3:1 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 the wide bandwidth ensures excellent linearity and low distortion. These features, combined with a wide input signal range, make the ADG793A/ADG793G the ideal switching solution for a wide range of TV applications, including RGB and YPbPr video switches. The switches conduct equally well in both directions when on. In the off condition, signal levels up to the supplies are blocked. The ADG793A/ADG793G switches exhibit break-before-make switching action. The ADG793G has two general-purpose logic output pins controllable through the I2C interface, which can be used to control other non-I2C-compatible devices such as video filters. The integrated I2C interface provides a large degree of flexibility in the system design. It has three configurable I2C address pins that allow the user to connect up to eight devices to the same bus to build larger switching arrays. The ADG793A/ADG793G operate from a single 3 V or 5 V supply voltage and are available in a compact, 4 mm × 4 mm body, 24-lead, lead-free chip scale package (LFCSP). PRODUCT HIGHLIGHTS 1.
