    Hey All.

    I'm pulling my hair out over this simple LPF circuit. I'm about to say I have a bad chip. So before I give up on it, I'd like to see if anybody has any experience with the SSM2044. I'm not getting anything out of it pre op-amp, the op amp is working. It's getting the correct voltages but, it just feels dead. What would be good is if someone knows the voltages, etc on each pin when working properly. I've build many LPFs based on the LM13600/Lm13700, Ca3080, even a TL702 and they all work perfectly. This is a dedicated LPF and it's giving me no joy :/
    Thanks in advance!
