1.功能LA7837/LA7838是由日本三洋公司生产的彩色电视机场锯齿波形成和场输出功率放大专用集成电路。该集成电路的作用是:在场触发脉冲控制下,产生场锯齿波信号,并对场锯齿波信号进行功率放大。然后将放大后的场锯齿波信号加在场偏转线圈上,为场偏
1. Function LA7837 / LA7838 is produced by Japan’s Sanyo color TV field sawtooth waveform and field output power amplifier ASIC. The role of the integrated circuit is: under the control of the field trigger pulse, the sawtooth signal is generated and the sawtooth signal of the field is amplified. The amplified field sawtooth signal is then applied to the field deflection coil for field bias
