Single Supply Servo Control Circuit

It is done, a complete circuit of how those single supply servos work, like the ones you would use for an arduino. Just like most circuits I’m interested in learning about the internet is devoid of information, but that does not stop me from figuring out your prebuilt magic modules. The two voltage sources are the Set Point and Feedback voltages respectively, there is 200mV of dead zone before the error voltage effects the motor, to ensure that tiny inaccuracies within the circuit don’t cause the motor to oscillate back and forth trying to compensate for them. I would challenge you to further understand how this circuit functions.
