GENERAL DESCRIPTION

The ADG736 is a monolithic device comprising two independ­ently selectable CMOS single pole, double throw (SPDT) switches.
These switches are designed using a submicron process that
provides low power dissipation yet gives high switching speed,
low on resistance, low leakage currents, and wide input signal
bandwidth.

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

ge. This ensures excellent linearity and low distortion when

ran
switching audio signals. Fast switching speed also makes the
part suitable for video signal switching.

The ADG736 operates from a single 1.8 V to 5.5 V supply,
mak

ing it ideally suited to portable and battery-powered

instruments.

Each switch conducts equally well in both directions when on, and
ea

ch has an input signal range that extends to the power supplies.

The ADG736 exhibits break-before-make switching action.

The ADG736 is available in a 10-lead MSOP package.
