The document describes the features and characteristics of the ADG733/ADG734 CMOS, 2.5V low voltage, triple/quad SPDT switches. They have low power consumption, selectable supply range, and break-before-make switching action.
The ADG733 and ADG734 are low‑power, dual‑supply CMOS analog switches offering three (ADG733) or four (ADG734) independent SPDT channels. They operate from a single 1.8 V‑5.5 V supply or a dual +2.5 V supply, making them suitable for battery‑powered instruments and data‑acquisition systems. All channels provide break‑before‑make switching and an EN pin to disable the device.
The datasheet includes detailed electrical specifications, absolute maximum ratings, pin configurations, truth tables, typical performance curves, and ordering information for the TSSOP and QSOP package options.
