Dimming signal 0-12V from microcontroller (logic level to 12V PWM)

[Zero999]

The magic smoke escaped from the MCP6H81 because 12.5V is greater than its rated maximum of 12V
(duh, but the router wall wart was the most convenient 12V supply I had kicking around),
so good thing I also ordered some TLV272s which are 16V tolerant.

Only when run off a 16V supply, otherwise the maximum rating of the inputs is 0.2V above the positive supply.
