GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
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掳C.
They are fully specified for
卤
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.
