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.
PRODUCT HIGHLIGHTS
1. Single- and dual-supply operation. The ADG633 offers
high performance and is fully specified and guaranteed
with ±5 V, +5 V, and +3 V supply rails.
2. Temperature range: −40°C to +125°C.
3. Guaranteed break-before-make switching action.
4. Low power consumption, typically <0.1 μW.
5. Small, 16-lead TSSOP and 16-lead, 4 mm × 4 mm LFCSP
packages.
