哪位大佬有BA6731A这个芯片的资料啊

了GND上(因为FXLS9xxxx的datasheet中显示此引脚接地),那MC33SA0528的GDNP_DSI0也是GND?请说一下这几个引脚的正确连接方式?

如题,我要做一个最高输出为20V,20A的功放,选用的是2SA1943和2SC5200这对功放管,并联起来用,要放大的信号有正弦也有直流。 我现在想要算出我需要几对管子,我手上有Datasheet

您好问下,单独调试tpl0501,用万用表量W和H两端电阻阻值有变化,但tpl0501的H接DRV612的GAIN引脚,tpl0501的W接地,不能控制DRV612运放的输出增益。DRV612

我在我的定制设计板上使用LIS2DH12进行BLE应用。 我注意到PCB的电流消耗大于预期,并且在进一步挖掘时发现加速度计在掉电模式下吸收过大的电流。彻底的测试表明,用于选择I2C地址的SA0线

我的型号PSA E4440A,最大。是-10dBm。我可以这样理解,如果进入SA的主信号为20dBm,SA输入衰减器应至少大于30dB,以确保混频器的信号电平不超过-10dBm? (2)如何最大。混合器Lvl设置
