GENERAL DESCRIPTION

The ADG4612/ADG4613 contain four independent single-

pole/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 each switch 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,

ensuring that no current flows, which can damage the switch or

downstream circuitry. This is very useful in applications where

analog signals may be present at the switch inputs before power

is applied or where the user has no control over the power supply

sequence.

In the off condition, signal levels up to 16 V are blocked. Also,

when the analog input signal levels exceed V

turns off.

The low 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.
