OPA454: OPA454 Disable function

Part Number: OPA454


Hi TI Support Team,

I've a strange behaviour concerning the Enable/Disable function.

I've a couple of OPA454, one is a basic non-inverting, the other is inverting ...

They should drive alternatevely a load and the E/D function is very useful for that, but ... What i observe during the simulation with TINA is:

For non-inverting configuration, the E/D works very well, while for inverting configuration the output is not really "disabled" and there is a residual of the signal ....

I join the TINA schematic, please run the transient analysis and look at VouP (the good) and VoutN (the bad) signals ...

Thanks in advance for your help.
