Function Generator using the CA3140

Here is a complete project which will help in learning to apply the CA3140 in a small instrument that could be used in your test bench along with the oscilloscope. It is necessary to study the datasheet for understanding the device and this application with full details. A function generator having a wide tuning range is shown in Figure 10. The 1,000,000/1 adjustment range is accomplished by a single variable potentiometer or by an auxiliary sweeping signal.

Analog OpAmp Circuits

The very first designs that came about were analog designs, a Vacuum Tube amplifier is an example. Analog is the representation of data or physical parameter in an accurate and precise decimal number like +72.182 mV. The greater the resolution required, the more demanding is the design for achieving high accuracy and low drift. As an analogy, see the conventional water tap as an analog control, an electric light ON-OFF switch as a digital control.
