Figure shows the operational amplifier universal CNC offset adjustment circuit. The imbalance change uses digital control. The integrated chip DAC-08C is used as the six D / A converter. ②, ④ are output pins, they externally connect with two l00kΩ resistors. These 2 resistor is equivalent to load resistance. It generates output voltage Vo1. The output voltage Vo1. It passes the two 4.7MΩ large resistors and turns to the A2 offset adjusting current. The two 4.7MΩ large resistors are set by the range of disorders. The circuit is useful to the big circuit system. Because virtually any offset voltage can be stored in the memory, you can add it to the the amplifier when it is necessary.
