集成功放电路以其优异的性能价格比,必然会在我国取代由分立元器件组成的音频功放,而用于收录机电视机等各个方面。随着产量迅速增加,自动测试是当务之急。手动测试费时费力,举一项参数的测试来看一看。例:功率的测试顺序: 插入器件→装上散热器→增加输入正弦信号→调失真仪满度值→调谐→读失真仪读数→如失真不到额定值则再增加输入重复上述过程直至失真度达额定值→读输出 Integrated amplifier circuit with its excellent cost performance, is bound to replace the audio amplifier composed of discrete components in our country, but for all aspects of radio and television receivers. With the rapid increase in production, automatic testing is a top priority. Manual testing takes time and effort, take a test of parameters to take a look. Example: Power test sequence: Insert device → Install heat sink → Add input sinusoidal signal → Adjust true distortion value → Tune → Read distortion instrument → Add input if distortion is less than rated Repeat the above process until distortion Rated value → read output
