GENERAL DESCRIPTION

The ADG633 is a low voltage CMOS device comprising three

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

switches. The device is fully specified for ±5 V, +5 V, and +3 V

supplies. The ADG633 switches are turned on with a logic low

(or high) on the appropriate control input. Each switch conducts

equally well in both directions when on and has an input signal

range that extends to the supplies. An EN input is used to enable

or disable the device. When the device is disabled, all channels

are switched off.

The ADG633 is designed on an enhanced process that provides

lower power dissipation, yet is capable of high switching speeds.

Low power consumption and an operating supply range of 2 V

to 12 V make the ADG633 ideal for battery-powered, portable

instruments. All channels exhibit break-before-make switching

action, preventing momentary shorting when switching channels.

All digital inputs have 0.8 V to 2.4 V logic thresholds, ensuring

TTL/CMOS logic compatibility when using single +5 V or dual

±5 V supplies.

The ADG633 is available in a small, 16-lead TSSOP package

and a 16-lead, 4 mm × 4 mm LFCSP package.
