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 VDD by VT, the switch
turns off.

SWITCHES SHOWN FOR A LOGIC 1 INPUT.
Figure 1.
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.
