... The input operational amplifier source is constant current. Since the 11 kΩ resistor between this and the next stage functions as the load, the input operational amplifier gain must be set carefully. *6: The braking operation is a short (to ground) braking operation. The sink side output this time. *7: Design guarantee. LA6565 ...
