GENERAL DESCRIPTION The ADG792A/ADG792G are monolithic CMOS devices, each comprising three 4:1 multiplexer/demultiplexers that are controllable through a standard I2C serial interface. The CMOS process provides ultralow power dissipation yet delivers 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 ADG792A/ADG792G the ideal switching solution for a wide range of TV applications, including RGB and YPbPr video switches. When turned on, the switches conduct equally well in both directions. In the off condition, signal levels, up to the supplies, are blocked. The ADG792A/ADG792G switches exhibit breakbefore-make switching action. The ADG792G also has two general-purpose logic output pins controllable through the I2C interface 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. To build larger switching arrays, the user can set the three I2C address pins allowing as many as eight devices to connect to the same bus. The ADG792A/ADG792G operate from a single 3 V or 5 V supply voltage and is available in a compact 4 mm × 4 mm body, 24-lead, Pb-free, LFCSP package. PRODUCT HIGHLIGHTS 1. 2. 3. 4. 5. 6.
