This is the basic full-scale circuit of an LM3914 for voltage measurement or voltage triggering and control. The power supply must be within the indicated range.
This circuit was obtained in a 1989 English magazine. Despite using a fixed 5 V regulator, it can...
With the feedback of the output circuit, the monostable acts as a frequency divider, that is, it...
In this circuit of an old American documentation, the input impedance is the same as the output...
