Low Voltage, 300 MHz Quad 2:1 Mux Analog HDTV Audio/Video Switch
The bandwidth of the ADG794 is typically 300 MHz and this, coupled with low distortion (typically 0.68%), makes the part suitable for switching analog audio/video signals.
The ADG794 operates from a single 3.3 V/5 V supply and is TTL logic compatible. The switches are controlled by the logic inputs IN and EN as shown in Table 4. The EN pin allows the user to disable all switches.
These switches conduct equally well in both directions when on. In the off condition, signal levels up to the supplies are blocked. The ADG794 switches exhibit break-before-make switching action.
The ADG794 is available in a 16-pin QSOP package.
