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 ...
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 ...
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 ...
