The WM signal is a digital signal with a fixed period and an indefinite duty cycle.If the counter of Timer_A works in the up-counting mode, the output adopts the output mode 7 (reset/set mode)to contr
Because the op amp is powered by a single power supply, a bias voltage VCM1 of tens of mV must be added (why?). I see that the classic differential amplifier circuits are all grounded? Also, I used a
LM4907 is an audio power amplifier designed for mobile phones and other portable communication devices. It can continuously transmit 1 W of average power to an 80 ohm load , powered by a 5VDC power su
