Kai,
Let me give you the exact application, I was thinking about use all 10K connected to P2 of an at89c52 to make the ladder, one op-amp to conect it to the 4051 input, and one more op-amp per output channel of the 4051 to send a control 0-10 V to an dimmer board that drives up to 4 KW AC triac for lighting. Can be done? (I was thinking to make the gain of the amps adjustable, so I can adjust it to 0-10 V, and I dont think that precision would matter much in this case.) gabriel |
