This sensitive touch potentiometer is based on IC1 (CA3130), one operational amplifier with a high input impedance. When the finger touches Se1 sensor, C2 (MKT type capacitor) is charged through the ...
This is a digitally controllable electronic potentiometer. The heart of the circuit is a 16 channel analog multiplexer. Controlled by the BCD value at the inputs, the output pin of the multiplexer ...
In many system applications, it becomes necessary to adjust a switched-mode power supply (SMPS) output voltage within narrow limits in order to remove tolerances and drops in the power path, verify ...
