U1A LF353 opamp turns on a buzzer when the voltage at Test + falls very low indicating a short between Test + and Test – […]
This amplifies the difference between two inputs Vp and Vn the low impedance of this configuration is a drawback, but can be used in analog […]
I would like to improve that circuit of a single digit voltmeter, I want to make it measure voltage from -9 V to +9 V […]
I have attached a document of the circuit explanation of my ultrasonic range meter. But now I want to know if Im going to insert […]
I need to know as making an amplifier with a port USB as music storage in a memory Flash, which circuit integrated as independent DAC […]
This is a a circuit from my Power Supplies Section. There may be some documentation errors in my circuits. If you are used to building […]
I will just explain part of this circuit. D9 and D10 provide a low cost -1.4 from -5 V. This is needed to reach near […]
