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 m SOIC package.
