增加IC运放的输出电压通常要增加大电压外接晶体管。然后形成的电路需要经过校正才能保持它的工作特性。这种校正是很困难的,尤其是对精密放大器而言。本设
Increase the output voltage of the IC op amp usually increase the voltage of the external transistor. The resulting circuit needs to be calibrated to maintain its operating characteristics. This correction is very difficult, especially for precision amplifiers. This set
