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 appro
priate 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 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.
