I've been using the HV507 for parallelization of a 300VDC supply, but the chip only has 64 channels. I was wondering how to drive this voltage to a much higher number of channels (say, 1,000).
Is this just a question of tracking down the highest-channel alternative to the HV507, and using as many in conjunction as necessary, or is there some special circuit I should employ for parallelizing a high DC voltage to an arbitrarily large number of channels? Is a custom IC necessary?
I'm very new to electronics and thus also to multiplexers and shift registers.
