Correct application circuit schematic diagram of UAA4002 when there is no negative power supply

Application of UAA4002 without negative power supply : In some application scenarios, the power supply of
the user's base drive circuit is a single power supply . At this time, the circuit in Figure 12-31 can be used to ensure the appropriate negative bias voltage for the normal operation of the UAA4002 . If the voltage drop of one diode is not enough to bias the UAA4002 normally , two or thirty-two diodes in series can be considered.
