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.
