From the implementation point of view, to realize the touch function, an RC oscillation comparison network, a comparator and a counter are required. The MSP430 has such resources, and its pin leakage
Help! I am using ADA4870 to make an amplifier circuit. When I input a 1.5MHZ 1V sine wave, why does the output signal only increase the voltage, but the amplitude of the sine wave is not amplified? Is
