Yes, it's a common anode nixie. But won't the limiting resistor drop the voltage to something below the ignition/maintaining voltage of the nixie if I put it before the anode? I do admit that it would be a whole lot simpler, PCB-design-wise.
I think I've got it...let's see:
At any one time, my driver will open only one channel. That particular channel, since it has current flow, will only see 5V since the voltage drops on the resistor. In the mean time, because there is no current flow on the other channels the resistors act like...
Here are some snapshots of the schematic:
That's what I'm trying to find out. Doesn't the fact that I put a 76k resistor before the driver drop the voltage to an acceptable level?
Or do I also need to put a PMOS on the anode for the case when all cathodes are off?
Sorry, I forgot to specify that the mosfet is part of the SCT2024.
Here is a schematic from the datasheet. I'm using the configuration on the left, except my "led" is ahead of the resistor and has a negligible voltage drop, so I'm relying on the resistor to drop it down to the specified...
Hello world! Says the newbee,
I've just started work on a nixie tube clock using Z573M tubes and I'm having some doubts regarding the driving. First of all, size is important, so I'm going for full SMD circuits (plus it's hard to find vintage nixie drivers and they're all TTL which makes...
