We are using Quad SPDT switch ADG1434, in one of our designs.
In our design, the input lines may be driven even when the power is off.
Below disucssion suggests that ADG1434 is not suitable for such applications.

Background of Application:
We have 4 independent analog signal lines that range from -12V to 12V coming from an external device.
Configuration of ADG1434:
Source Terminals A : Input analog signals from external device
Source Terminals B : Gro…
Hello,just wanted to ask if the ADG1434 switch is based on the AEC-Q qualification standard?Thanks in advanceMohammad
Could you please let me know if ADG5434 & ADG1434 EPAD is connected to VSS internally .
We see that it seems not to be connected internally .
ADG1434: Exposed Pad. The exposed pad is tied to the substrate, VSS .
ADG5434:The exposed pad is connected…
A regulated supply for the ADG1434 is not required, but you need to understand that the on resistance of the channel will change with supply voltage. This is presented in the datasheet on page 10, figure 10.
However, it is not recommended…
You should have a look at the ADG5434. The ADG5434 is pin for pin compatible with the ADG1434 but comes with a much wider supply range. It can operate with a single supply from 9 V up to 40 V.
If you have any other questions please let me know.
I am using the ADG1434 quad switch and we are having what appear to be ESD failures. Using a curve tracer, we can see 20-25uA @ 0.5V between pin 1 and VSS on two different failed parts. We have one more failed part that is closer to a dead short…
I've got offset voltages of 0,2V with a device containing ADG333ABNZ. Do the pin compatible newer versions like ADG1434 or ADG5434 correct this?
We are using ADG1434(YRUZ) biased at +15V for Vdd, -15V for Vss. The power input for the chip is from an APS rated at +/-15V and +5V with 10% trim (min).
During our experiment, we use several sets of chips, and one set of the chips was burned.
