There are literal drop-in replacements for the LM741, such as the TLC081 (not to be confused with the similarly named FET-input TL081), which has 32 times the slew rate, 10 times the gain ...

But should it be? Perhaps not, as [More Than Electronics] reveals with this head-to-head speed test that compares the 741 with its FET-input cousin, the TL081. The test setup is pretty simple ...

The amplifier is a textbook non-inverting amplifier using a TL081 op amp. Note that there are many suitable operational amplifiers that may be used and some are better for audio than others. R4 & R5 ...

The circuit is a microphone amplifier for use with low impedance (~200 ohm) microphones. It will work with stabilized voltages between 6-30VDC. If you don’t build the impedance adapter part with T1, ...

The current source is implemented using a type TL081 opamp. The output current of the opamp flows through the diode and R2. This simple LED tester consists of a current source with a potentiometer ...

The circuit is built around commonly available JFET input op-amp TL081 and a few precision resistors. It has a wide operating range from 0-10 nA to 0-1 A in steps of multiplicative decades. the range ...

This order 4 filter need only one OA IC , so we can achieve lower distorsions, lower intermodulation … Resistors values represent the load on the OA output, the maximum TL081 load is 2kΩ . R1-R4 build ...
