We manufacture a product which uses the TLC2274ID.
Each op-amp stage is used as a voltage follower and usually has an external sensor connected.
It has been suggested that we have a variant which leaves off one of the external sensors which means that the input to one of the op-amp stages will be floating. There is no pull down resistor. There are 2 filter capacitors to ground. We can't really alter the PCB.
Common knowledge says that floating inputs can take current but my question is how much current? Could the device become damaged/ go into a fault condition?
Thanks for your help
