GENERAL DESCRIPTION
The ADG794 is a monolithic CMOS device comprising four
2:1 multiplexers/demultiplexers with high impedance outputs.
The CMOS process provides low power dissipation yet gives high
switching speed and low on resistance. The on-resistance variation
is less than 1.2 Ω over the input signal range.
The wide bandwidth of the ADG794 (300 MHz typical), coupled
with low distortion (0.18% typical), 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-lead QSOP.
