CMOS, ±5 V/+5 V/+3 V, Triple SPDT Switch
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.
- 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.
