Many situations require a precision voltage source which
can be adjusted through zero to both positive and negative
output voltages. An example is a bipolar power supply.
Have you ever adjusted your unipolar lab supply down to
0V, then swapped the output leads and adjusted it back up to
get a negative voltage output? What happened to your circuit
when the input from the low impedance source went open
circuit? Were you able to actually adjust the output to 0V, or
did a small voltage offset limit the range? This precision
bipolar voltage source can solve these problems.
