Product Details

The ADG4612 & ADG4613 contain four independent singlepole/ single-throw (SPST) switches. The ADG4612 switches are turned on with Logic 1 on the appropriate control input. The ADG4613 has two switches with digital control logic similar to that of the ADG4612; 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 ADG4613 exhibits break-before-make switching action for use in multiplexer applications.

When no power supplies are present the switch remains in the OFF condition and the switch inputs are high impedance inputs. This ensures that no current flows that may damage the switch. This is very useful in application where analog signals may be present at the switch inputs before power or where the user has no control over the Power Supply Sequence.

In the off condition, signal levels up to 16V are blocked. Also, if the analog input signal levels exceed VDD by VT then the switch will turn off.

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.
