We found this circuit in an old documentation. The operational can be of any type and the frequency is given by the formula next to the diagram.
In the figure we have a high stability voltage reference, providing a voltage of 10 V at the...
The SAA1027 integrated circuit was specifically developed to control stepper motors with a 500mA...
The sampling and retention circuit shown in the figure uses the LM108. In this circuit we have two MOS...
