LM741 has only one op-amp inside, there are some op-amp IC’s having more than one op-amp like LM358, LM148, LM248, LM348 Provided with short circuit and overload protection. Low power consumption. Large common mode rejection ratio (CMRR) and differential voltage ranges. ...
A standard op-amp IC 741 is constructed with a circuit containing 20 transistors and 11 resistors. All these transistors and resistors are integrated into a single monolithic chip. The internal connections of these components are illustrated in the figure shown below. ...
Testing a 741 IC Testing a 741 IC It is important to make sure that the op-amp which we have is working properly, before we proceed to further experiments. Here is a simple method to test a 741 IC, with the minimum components and circuit connection ...
A simple circuit for converting a floating dual power supply is shown here.The circuit is based on auA 741 op-amp. The input supply is splitted by the voltage divider circuit formed of R1 & R2 ,and given to the non-inverting input of the IC1. The output (Pin 6) is connected to the...
