OK...here's an absolute rarity: I feel completely brain dead in solving this particular problem.
I've got a PIC18F65K90 with which I want to drive the SHDN pin of an LTC2050. Currently, RF7 of the PIC is used to drive the pin.
SHDN must be less than 0.5V (low) to shutdown, and greater than V+ - 0.5V (high) to enable the amp.
