GENERAL DESCRIPTION

The ADG704 is a CMOS analog multiplexer, comprising four

single channels. This multiplexer is designed on an advanced

submicron process that provides low power dissipation yet gives

high switching speed, low on resistance, low leakage currents

and high bandwidths.

The on resistance profile is very flat over the full analog signal

range. This ensures excellent linearity and low distortion when

switching audio signals. Fast switching speed also makes the

part suitable for video signal switching.

The ADG704 can operate from a single supply range of +1.8 V

to +5.5 V, making it ideal for use in battery powered instru-

ments and with the new generation of DACs and ADCs from

Analog Devices.

The ADG704 switches one of four inputs to a common output,

D, as determined by the 3-bit binary address lines, A0, A1 and

EN. A Logic “0” on the EN pin disables the device.

Each switch of the ADG704 conducts equally well in both

directions when ON. The ADG704 exhibits break-before-make

switching action.

The ADG704 is available in 10-lead

µSOIC package.
