ADG4612BRUZ Datasheet PDF - ADI

●The ADG4612BRUZ is a single-pole single-throw (SPST) quad CMOS Analog Switch turns on with logic 1 on the appropriate control input. It has two switches with digital control logic. 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 16V are blocked. Also, when the analog input signal levels exceed VDD by VT, the switch turns off. 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.
