GENERAL DESCRIPTION

The ADG1611/ADG1612/ADG1613 contain four independent

single-pole/single-throw (SPST) switches. The ADG1611 and

ADG1612 differ only in that the digital control logic is inverted.

The ADG1611 switches are turned on with Logic 0 on the

appropriate control input, while Logic 1 is required for the

ADG1612 switches. The ADG1613 has two switches with

digital control logic similar to that of the ADG1611; 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. In the off condition, signal levels up to

the supplies are blocked.

The ADG1613 exhibits break-before-make switching action for use

in multiplexer applications. Inherent in the design is the low charge

injection for minimum transients when switching the digital inputs.

The ultralow on resistance of these switches make them ideal

solutions for data acquisition and gain switching applications

where low on resistance and distortion is critical. The on resistance

profile is very flat over the full analog input range, ensuring

excellent linearity and low distortion when switching audio signals.

The CMOS construction ensures ultralow power dissipation, making

them ideally suited for portable and battery-powered instruments.
