Power Amplifier Circuit using IC 741 and MOSFET
In this post we study a power amplifier design configured using an ordinary IC 741 and a couple of MOSFETs. An operational amplifier’s output power such as from an IC […]
IC 741 Power Supply Circuits
In this post I have explained how to make simple yet fully stabilized and regulated, variable power supply circuits using the IC 741 op amp. Three versions of the 741 […]
Comparator Circuits using IC 741, IC 311, IC 339
The basic function of a comparator circuit to compare two voltage levels at its input pins and produce an output to show which input voltage has higher potential than the […]
How to Set IC 741 for Auto Cut-oFF
In this post I have explained how to set or adjust an opamp 741 IC based battery charger circuit for implementing an automatic cut-off for the connected battery once it […]
Simple Soil Moisture Tester Circuit with a Single IC 741
A very simple mud or soil moisture tester circuit can be built by using a single opamp and a few passive components, I have explained the details through the following […]
