Folks,
Im designing an analog circuit that should take a voltage from a pot, remove offset, output 2 complementary analog voltages. The circuit has both positive and negative supply rails, but the lower end of the pot should be grounded. Signals are DC. Low output impedance would be nice.
I have an idea about how to achieve this with 2 instrumentation amps. Heres the schematic
But I wonder, is theres a more elegant way of achieving this with 2 or so OpAmps?
Any suggestion, insight or reference is really appreciated!
Cheers,
- Nick
