single-supply bridge circuit
split rails
single rail operation
the U1 amplifier servos the bridge while maintaining the voltage across the parallel combination of 2.55 MΩ and 6.19 kΩ to generate a 200 μA current source.（servos the bridge？？）
One of the biggest problems with the part in today’s environment is that the OP07 requires dual supplies.
