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.
