GENERAL DESCRIPTION

The ADG611, ADG612, and ADG613 are monolithic CMOS

devices containing four independently selectable switches. These

switches offer ultralow charge injection of 1 pC over full input

signal range and typical leakage currents of 10 pA at 25

°C.

They are fully specified for

±5 V, +5 V, and +3 V supplies.

They contain four independent single-pole/single-throw (SPST)

switches. The ADG611 and ADG612 differ only in that the

digital control logic is inverted. The ADG611 switches are turned

on with a logic low on the appropriate control input, while a logic

high is required to turn on the switches of the ADG612. The

ADG613 contains two switches whose digital control logic is

similar to the ADG611, while the logic is inverted on the other

two switches.

Each switch conducts equally well in both directions when ON

and has an input signal range that extends to the supplies. The

ADG613 exhibits break-before-make switching action. The

ADG611/ADG612/ADG613 are available in small 16-lead

TSSOP packages.
