GENERAL DESCRIPTION

The ADG1636 is a monolithic CMOS device containing two

independently selectable single-pole/double-throw (SPDT)

switches. An EN input is used to enable or disable the device.

When disabled, all channels are switched off. Each switch

conducts equally well in both directions when on and has

an input signal range that extends to the supplies. In the off

condition, signal levels up to the supplies are blocked. Both

switches exhibit break-before-make switching action for use

in multiplexer applications.

The ultralow on resistance of these switches make them ideal

solutions for data acquisition and gain switching applications where

low on resistance and distortion is critical. The on resistance profile

is very flat over the full analog input range, ensuring excellent

linearity and low distortion when switching audio signals.

The CMOS construction ensures ultralow power dissipation,

making the parts ideally suited for portable and battery-

powered instruments.
