Today, 17:50KlausST replied to a thread How to generate Frame Clock(FR) of the ADC? in Digital Signal ProcessingHi, I used the LTC2170, which has an identical interface. Defective IC is possible, but I think itīs not very likely. You know that they are...4 replies | 105 view(s) -
Today, 11:25KlausST replied to a thread SCR speed brushed DC 180v motor control does not work in Analog Circuit DesignHi, Brian is correct. It is very dangerous. And the OP seems not to be experienced enough to know and keep on safety regulations. I donīt want...10 replies | 243 view(s)
