It also features short circuit protection and internal frequency compensation circuits built in it.
741 op amp voltage swing. The high gain and wide range of operating voltage provide superior performance in intergrator summing amplifier and general feedback applications. Ic 741 op amp can provide high voltage gain and can be operated over a wide range of voltages which makes it the best choice for use in integrators summing amplifiers and general feedback applications. The waveforms in figure 2 show the input and output signals of the lm741 non inverting amplifier circuit.
The lower the load resistance the lower the allowable voltage amplitude. Limiting the output current also limits the allowable output voltage swing. V dd or v ss under defined operating conditions where the op amp still can function correctly.
The lm741 series are general purpose operational amplifi ers. The lm741 series are general purpose operational amplifi ers which feature improved performance over industry stan dards like the lm709. Typical output voltage swing of 741 opamp is 14v when the supply voltage is 15v and load impedance is greater than 10kw.
The key to comparing voltage output swing specifications is to determine the amount of current that the amplifier is sinking or sourcing. Output voltage swing defines how close the op amp output can be driven to rail to rail either power rail. This will vary depending on the output load impedance and supply voltage.
For 741 opamp svrr is 150uvv. This is about all that is permitted by common mode limits for a 15 volt supply so the output impedance is not a serious limitation. They are direct plug in replacements for the 709c lm201 mc1439 and 748 in most applications.
The input signal is 106 vpp and the output signal is 194 vpp. Op amps with mos transistor outputsca3130. The blue waveform top shows the input signal while the red waveform bottom shows the output signal.
Device information1 part number package body size nom ua741cd soic 8 490 mm 391 mm ua741cp pdip 8 981 mm 635 mm ua741cps so 8 620 mm 530 mm 1 for all available packages see the orderable addendum at the end of the data sheet. For a load 2k the 741 can swing to within about 2 volts of the supply. It is the maximum positive or negative output voltage that can be obtained without wave clipping.
It is intended for a wide range of analog applications. The ua741c device is characterized for operation from 00c to 700c. For lower load impedances however the safe output voltage swing will be progressively curtailed.
