With a capacitive load, a constant-current source will produce a triangular waveshape. With the common electrode grounded, each segment could be driven with a totem-pole driver to roughly +100v and -100v. When I say 'roughly', I mean there will need to be some tweaking, and it will probably be somewhere between 100-150V. Constant-current drivers are very simple to design; the challenge here is to make reliable high-side and low-side drivers. Since the operating speed is only a few hundred Hz, you could use opto-isolators to serially shift-in segment data. The triangular waveform really isn't the end-goal; it's actually a consequence. What really matters in my opinion is the current. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
