用SN76001替代TBA820;这是美国得克萨斯公司的产品,其外形是双列直插式⒁脚结构,各管脚的功能与TBA820、SL345和LA4100等各类产品均不同,可见于表1。除表中已标出的管脚外,②、⑥、⑨、⑾和⒀脚均为空脚。而它的功能则与TBA820极为相似。替代时只要按功能把管脚焊好,如果出现自激现象,电源输出端即TBA820⑥脚与地之间再并联一只50～100μF的电解电容器。 Use SN76001 instead of TBA820; This is the product of the Texas of the United States, its shape is dual in-line ⒁ foot structure, the function of each pin and TBA820, SL345 and LA4100 and other products are different, can be found in Table 1. In addition to the table has been marked pins, ②, ⑥, ⑨, ⑾ and ⒀ feet are empty feet. And its function is very similar with TBA820. As long as the alternative function as long as the pin welding, if there is self-excited phenomenon, the power output that is TBA820 ⑥ foot and ground in parallel with a 50 ~ 100μF electrolytic capacitor.
